+\S2{cmdTrimDraw} Trim a Draw Object using another Draw object
+
+The \f{Trim Draw} command can be used to trim many draw objects (Straight Lines, Curved Lines, Circles, Polygons, PolyLines). Polygons and Circles are split into PolyLines and Curves.
+
+\n First a Trimming object (draw object) is selected with \f{Left-Click}. Until the trim draw object is selected, a draw object under the cursor will be highlit in blue. Once it is selected it will be highlit in the current Select Color.
+
+\n Next the point of intersection between the trim object and an object to be trimmed is selected. Until a split point is selected, a suitable split point under the cursor will have a blue trim anchor that is a T shape aligned with the trimming object.
+
+The trim anchor base has an arm that indicates which side of the trimmed object will be deleted. A \f{Left-Click} will trim the object.
+
+\u000
+
+If the trimmed object is a circle or a polygon, the result will be the same as a Split (\K{cmdSplitDraw}), a 355 degree circle and an open polyline with ends at the split will result.
+
+Once a trim has occured, the trimming object remains selected for another trim.
+
+To leave the command use the spacebar. If \e{Sticky} (\K{cmdSticky}) is set for Split commands you will be able to select another trim object.

+The \f{MagneticSnap} feature eases constructing and assembling Tracks and Draw objects by "snapping" the end of new objects to existing objects. 
+For existing track objects the point snapped to is always an open end point. 
+The snap operates when "close" to the object (a few pixels distant) and an anchor point (a blue circle) is displayed when this will occur if the mouse is clicked. 
+
+\u000
+When Adding Draw line objects, the snap point is the nearest point on the existing object. 
+A snap to the end of a line object can be selected by positioning the cursor close to the end of the line but off it, in the direction of the line. This will ensure the closest point is the end.

+
+If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.

+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.

+<h1><a name="index"></a>Chapter 1: Introduction To <em>XTrackCAD</em></h1>
+<p>
+<em>XTrackCAD</em> is a CAD (computer-aided design) program for designing Model Railroad layouts. <em>XTrackCAD</em> supports any scale, has libraries of popular brands of turnouts and sectional track (plus you add your own easily), can automatically use spiral transition curves when joining track and has extensive on-line help and demonstrations. <em>XTrackCAD</em> lets you manipulate track much like you would with actual flex-track to modify, extend and join tracks and turnouts. Additional features include tunnels, 'post-it' notes, on-screen ruler, parts list, 99 drawing layers, undo/redo commands, bench-work, 'Print to Bitmap', elevations, train simulation and car inventory.
+</p>
+<p>
+Using it, you can
+</p>
+<ul><li>
+Design layouts in any scale and gauge,
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+Use predefined libraries for many popular brands of turnouts to help you get started easily,
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+Add your own favorite components,
+</li>

+<ul><li>
+Print the design in a scale of your choice. When printed in 1:1 scale the printout can be used as a template for laying the track to build your dream layout.
+</li>
+</ul>
+<p>
+
+</p>
+<p>
+New users should run the demonstrations (via the <strong>Help&gt;Demos</strong> menu) to get an overview of the many features of the program. A number of example layout designs are also available.

+<h1><a name="whyXTrackCAD"></a>1.1 Why Choose <em>XTrackCAD</em></h1>
+<p>
+<strong>Why Choose XTrackCAD</strong>
+</p>
+<p>
+<strong>Easy to use</strong>
+</p>
+<p>
+<em>XTrackCAD</em> was designed to operate in a similar way to pencil and paper: You can draw tracks by dragging the mouse, you select and place turnout "templates" anywhere on existing tracks, and you can use fixed radii for initial design.
+</p>
+<p>
+But extra capabilities have been added that give more power by using Flex-tracks (Cornu) you have tracks that automatically redraw as you drag turnouts around, creating smooth curves, you can zoom in and out, and of course, undo and deleting tracks are easier!
+</p>
+<p>
+You don't have to be an expert CAD user to make the most of <em>XTrackCAD</em> but the program will ensure that dimensions, radii and angles are accurate.
+</p>
+<p>
+You don't have to specify line lengths or angles and just draw. But if you want to be more precise, you can enter precise dimensions both in real-world and scale sizes.
+</p>
+<p>
+<em>XTrackCAD</em> is a specialized CAD for railway modelling, it deals with tracks as tracks, not as line segments. Tracks are connected correctly to each other and with endpoints of turnouts and other components.
+</p>
+<p>
+As you zoom in, the two rails are drawn and then ties are added.
+</p>
+<p>
+<strong>Free</strong>
+</p>
+<p>
+Thanks to the generosity of Dave Bullis, who wrote the progam, and the active help of open-source volunteers, XTrackCAD is free to own and use. You can even take up the cudgels and help!
+</p>
+<p>
+<strong>Available Help</strong>
+</p>
+<p>
+On-line demonstrations show the actual operation of many of the program's features. Extensive help is available for all commands and operations. There are communities of users and developers who can answer quaestions.
+</p>
+<p>
+<strong>Packed with features</strong>
+</p>
+<p>
+<em>XTrackCAD</em> is designed from the ground up to be a complete tool for many aspects of Model Railroad layout design.
+</p>
+<dl><dt>
+<em>Active UI Prompting</em>
+</dt>
+<dd>
+As the mouse moves over the layout objects, a set of different anchors are shown to indicate what is possible in each command with each modifier key if clicked or double clicked at that location.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dt>
+<em>Train Simulation and Car Inventory</em>
+</dt>
+<dd>
+Any number of Cars and Locomotives can be placed on your layout to check clearances, siding capacities and track layout. Trains can be animated to simulate operations and switching on your layout.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+The Car Inventory dialog records your cars and locomotives and these can be exported and imported from spreadsheets.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dt>
+<em>Track Manipulation</em>
+</dt>
+<dd>
+Track segments can be lengthened or shortened by simple click and drag. Tangents to a curve are created by dragging away from the curve. Tracks are extended by dragging from an Endpoint, creating new straight or curved segments. New tracks can be snapped into place or precisely placed and then Joined.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+Track circles are especially handy for determining overall designs and seeing what will fit in a given area.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+The Cornu flex-track features create dynamically variable tracks that optimise the curvature of tracks to ensure a protypical appearance. They alter as the other tracks are moved just as flex-track will in the 12 inches to the foot world!
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+The Parallel command easily creates new straight or curved tracks, laying out yards and sidings in a few easy steps. Accurate platforms can be created with the Parallel Lines command followed by the Join Lines command.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+The Join command links any two tracks (Straights, Curves, Turnouts or Turntables) with accurate aligned connecting track segments which can be easements including Cornu easements. The connected tracks are trimmed or extended as required.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+The Helix Track command computes the number of turns, radius, grade and vertical separation based on your criteria.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+Turntables can be constructed with any radius and can either have fixed or dynamic bay tracks
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dt>
+<em>Turnout Select and Placement</em>
+</dt>
+<dd>
+The Turnout Hot Bar contains a scrolling list of Turnouts, Sectional Tracks and Structures available in the current Scale. Simply click on one and click again drop it onto the layout.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+As Turnouts are dragged over existing tracks they are automatically aligned. <em>XTrackCAD</em> searches for any other tracks that align with each of the Turnout's Endpoints, and shows you the number of connections that will be made and the maximum offset as you position the Turnout. Just adjust the Turnout's position to minimize the offset to ensure the best fit.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+When a turnout is placed, each Endpoint is examined to see if it aligned to an existing track. If so, the track is split to create a perfect connection to the turnout. Placing Turnouts is a 'snap'.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dt>
+<em>Layers</em>
+</dt>
+<dd>
+Layers are an important feature for manageing the design for layouts of any complexity. Use one layer for the main-line and others for staging tracks, Bench-work or scenery. Multilevel designs can have groups of layers for each level.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<em>XTrackCAD</em> allows up to 99 layers layers can have their own button to control visibility. Each layer can have a name which is displayed as the balloon help for the layer button.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+Modular Layout assembly is supported with Modular Layers which ensure thier contents are moved as a set.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+Tracks and other objects can be colored according to which layer they are in. Also, each layer can be frozen to prevent accidental changes to parts of the layout that are finalized.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dt>
+<em>Elevations and Profile</em>
+</dt>
+<dd>
+Elevations are one of the most powerful features of <em>XTrackCAD</em> they are dynamically recalulated as the layout changes.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+Traditional layout designs (such as published in magazines) show elevations at selected spots on the layout. They may also show grades between elevations. These can be input into XtrkCAD.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<em>XTrackCAD</em> lets you define the elevation of any Endpoint on the layout. You can also have <em>XTrackCAD</em> automatically compute the elevation and grade between defined elevation points. You can define the elevation at the bottom and top of a sloped track, then have <em>XTrackCAD</em> compute the elevation at each riser position between.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+Once you have defined a few elevations, you can display the Elevation Profile for the layout along a path of connected track segments. The Profile display shows the length of the track, the elevation of each defined elevation point and the grades between them. You can even adjust the elevations directly on the Profile display.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dt>
+<em>Easements (Cornu Transition Curves)</em>
+</dt>
+<dd>
+Easements are special sections of gradually curving track used to connect straight and curved tracks (or two curved tracks). Easements reduce the effects of sudden changes in track curves which can cause derailments. They also look great!
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<em>XTrackCAD</em> can use Easements anytime the radius of the track changes. The Modify and Join commands will automatically insert Easement Track segments whenever needed. Each Easement is computed based on the radius of the neighboring tracks. You don't even have to think about it!
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dt>
+<em>Flexible and Powerful Printing</em>
+</dt>
+<dd>
+Printing is an important part of a layout design program, and <em>XTrackCAD</em> has a flexible Print command to get your design onto the layout.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+Printing is used for many purposes:
+<ul><li>
+A snapshot of the whole layout.
+</li>
+<li>
+Detailed closeups to examine areas of complicated track work.
+</li>
+<li>
+Full 1:1 for direct transfer to the layout.
+</li>
+</ul>
+
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+The Print command lets you scale the printout from a one page overall view (with the handy Snap-Shot button) right up to full size 1:1.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+Multiple page printouts are easy to do. A gird representing each page is drawn over the layout and you can click on the pages you want to print. The gird can be moved and rotated to any position so the orientation of the printout matches your layout. Pages can be printed in Portrait or Landscape format.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+At 1:1, registration marks can be printed every 3" (or 10cm) to help align different sets of printouts. Also, the roadbed outline can be drawn at a user-specified width to assist cutting the roadbed from sheet material.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dt>
+<em>Turnout and Structure Creation</em>
+</dt>
+<dd>
+<em>XTrackCAD</em> comes with Turnout, Sectional Track and Structure Parameter Files for many brands of tracks and accessories. However, your brand may not supplied. The Turnout Designer dialogs and the Group command make it easy to add your own custom definitions.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+The Turnout Editor has separate screens for designing Turnouts (Regular, Curved, Wye and 3-way), Crossings, Slip-switch, Crossovers and Sectional Track. In each dialog a few measurements are required to create a new definition. Full size printouts can be made directly from the dialog to check your design.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+The Group command can create Structure definitions from selected tracks, lines and shapes. You can make structures as simple as a rectangle or highly detailed. You can also modify existing designs to add details or make adjustments.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dt>
+<em>Lines, Shapes, Table Edges, Text and Notes</em>
+</dt>
+<dd>
+Layout designs are more than track!
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+The <em>XTrackCAD</em> Draw command is used to draw lines (straight, curved and circles) and shapes (filled boxes, circles, polylines and polygons). These can be different colors and lines can have different widths. The Polylines and Polygons can have curved sides. These are useful for drawing scenic features (rivers, bridges, mountains).
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+You can add Bench-work and dimension lines too.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+Special types of lines are drawn by the Table Edge command are used to represent the boundary at the edge of the layout.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+Text can be added to the layout.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+Notes can be attached to particular spots on the layout. When selected they can display special information about that part of the layout, such as prototype features, construction details or operation notes. This includes URL links to files on the Internet.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dt>
+<em>Parts and Price Lists</em>
+</dt>
+<dd>
+The Parts List command generates a list of the number of the different types of Turnouts, Sectional Track and Structures selected on the layout. You can select everything or just the areas you are working on. As well, the total length of flex-track (for each track scale/gauge used on the layout) is listed.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+You can enter the price of each type of Turnout, Sectional Track and Structure, plus the length and price of flex-track. <em>XTrackCAD</em> will compute the price of each types and the grand total. The total number of flex-track sections is also listed.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dt>
+<em>Support for Sectional Track</em>
+</dt>
+<dd>
+Numerous Sectional Track Parameter Files are included with <em>XTrackCAD</em> (Atlas, Marklin, Peco, ...). The Hot Bar allows easy selection.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+The automatic alignment feature of Turnout and Sectional Track placements makes track pieces just 'snap' together.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+The Connect Track command adjusts Sectional Track to smooth out the slight gaps that can arise when working with Sectional Track.

+<h1><a name="addFeatures"></a>1.3 Additional <em>XTrackCAD</em> Features</h1>
+<p>
+<em>XTrackCAD</em> has many other carefully selected features:
+</p>
+<ul><li>
+Sections of track can be hidden, which can be drawn as dashed lines, or completely hidden. A Tunnel Portal is drawn when a hidden track connects with normal track.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+Sections of track can be tagged as bridge tracks which draws a bridge parapet on each side.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+Drawing Turntable stall tracks is easy, just drag from the Turntable with the Modify command. The minimum angle between tracks can be set to ensure accurate, evenly spaced tracks.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+Connections to non-visible layers are marked to an arrow head to show you the track continues on another layer.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+The Group command can be used to decorate custom designed Turnouts and Sectional Track with details to indicate switch machines, ground throws and power connections.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+Custom designed Turnouts can be modified, renamed or deleted with the Custom Management dialog.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+Flex-track connected to Turnouts is labeled with the total length to aid cutting flex-track to length.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+An on-screen ruler can be user to measure arbitrary distances.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+At 1:1 drawing (and printing) scale the track center line is drawn to make it easy to position roadbed and track.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+The balloon help for the Undo and Redo buttons shows the command that would be Undone or Redone.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+The Snap Grid can positioned at any origin and any angle. It can also be printed to help when transferring coordinates to the layout.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+The Map window is used to position the Main window on the layout. It can also be used to change the drawing scale.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+You can rescale and flip objects, trim turnouts and create block gaps.
+</li>
+</ul>

+<h1><a name="introQT"></a>1.7 Quick Tour</h1>
+<p>
+<img src="png.d/main.png">
+</p>
+<p>
+When <em>XTrackCAD</em> starts, it displays the <strong>Main</strong> (<a href="mainW.html#mainW">Section 3.1</a>) and <strong>Map</strong> (<a href="cmdMap.html#cmdMap">Section 3.2.2</a>) windows. The <strong>Map</strong> window is used to change the origin of the <strong>Main</strong> window when the entire layout cannot be displayed at one time.
+</p>
+<p>
+<img src="png.d/maintagged.png">
+</p>
+<p>
+The Menu Bar across the top of the <strong>Main</strong> window contains standard Windows menus. Some of these are particularly useful to the new user:
+</p>
+<ul><li>
+The <strong>File&gt;Exit</strong> menu exits <em>XTrackCAD</em>. You can also exit by selecting the System menu in the upper left corner of the Window.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+The <strong>File&gt;Open</strong> menu opens existing layout files and archives. When first installed, the default directory contains some example programs you can look at.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+The <strong>Help</strong> menu can be used to read the <em>XTrackCAD</em> Help file. Also, the <strong>Help&gt;Demos</strong> menu selects a number of demonstrations which illustrate various features of <em>XTrackCAD</em>.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+The <strong>Options&gt;Layout</strong> menu specifies the working scale and overall room size.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+The <strong>Options&gt;Preferences</strong> menu specifies some less frequently changed items. You can use this menu to choose Metric units (<a href="cmdPref.html#cmdPref">Section 2.10.7</a>).
+</li>
+</ul>
+<p>
+
+</p>
+<hr>
+<p>
+The Tool Bar contains icons for each of the commands in the Menus. The icons shown can be customized using the <strong>View-&gt;ToolBar</strong> submenu.
+</p>
+<ul><li>
+The main drawing Mode command is <strong>Select</strong> - which is shown with the red arrow icon. From this mode, selected objects can be <strong>Modified</strong> as well. A close second is the <strong>Describe</strong> mode which allows properties of Objects to be seen and Changed.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+A different mode is <strong>Train</strong> which allows trains to be simulated on the Layout.
+</li>
+</ul>
+<p>
+
+</p>
+<p>
+Under the Tool Bar is the Hot Bar. This contains defined track and drawing objects taken from parameter files. To use a template you select it and then click on the Drawing Area.
+</p>
+<hr>
+<p>
+The main part of the window is the Drawing Area, this is where the Layout is shown in 2D. The view can be zoomed or panned. The <strong>Pan-Zoom</strong> command whise symbol is the crossed arrows allows easiest control, but in <strong>Select</strong> command you can pan with the arrow keys and zoom with the trackpad or mousewheel or <strong>Ctrl</strong>+"+" or "-" can affect the zoom level.
+</p>
+<hr>
+<p>
+At the bottom on the screen are two more areas. The Status Bar contains messages about commands as they are being used, and the Info Bar shows the zoom level and the position of the cursor.

+<h1><a name="dirOverview"></a>1.9.1 <a name="i0"></a>Directories Overview</h1>
+<p>
+<em>XTrackCAD</em> uses two directories on your system:
+</p>
+<ul><li>
+The <em>XTrackCAD Install</em> directory, which contains the data and parameter files used by <em>XTrackCAD</em>.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+The <em>XTrackCAD Working</em> directory, which contains configuration and Check Point files.
+</li>
+</ul>
+<p>
+On MS Windows, the <em>Install</em> directory is set when you install <em>XTrackCAD</em>. All data files (parameters, demos, examples) can be found in the <code>share/xtrkcad</code> subdirectory underneath the <em>Install</em> directory. The <em>Working</em> directory is in your personal profile.
+</p>
+<p>
+On Linux, the <em>Install</em> directory is usually <code>/usr/local/lib/xtrkcad/</code>, but you can change this by defining the <code>XTRKCADLIB</code> environment variable before starting <em>XTrackCAD</em>. The working directory is <code>{HOME}/.xtrkcad/</code>.
+</p>
+<p>
+On Mac OSX, the <em>Install</em> directory is the application package, usually located in the <code>/Applications</code> directory. All the included parameters, demos and examples can be found inside the package under the <code>/Applications/xtrkcad/Contents/Resources/xtrkcad</code> directory. The <em>Working</em> directory is created as <code>.xtrkcad</code> - a hidden directory - under the active user's directory in <code>/Users</code>
+</p>
+<p>
+Layout files (<code>*.xtc</code>) and export (<a href="cmdExport.html#cmdExport">Section 2.5.1</a>) files (<code>*.xti</code>) can be saved anywhere you wish, as specified in the <strong>Save File</strong> and <strong>Open File</strong> dialogs.
+</p>
+<p>
+In MacOS Catalina, the program has no access to certain directories - the Documents and Download directories in particular.
+</p>
+<p>
+Example layouts can be found in the <code>example</code> directory under the <em>XTrackCAD</em> install directory.

+<h1><a name="bugs"></a>1.11.1 Reporting <a name="i0"></a>Bugs</h1>
+<p>
+If you encounter an unreported bug please submit detail regarding such to the <strong>Bug Tracker</strong> located at the <a href="https://sourceforge.net/p/xtrkcad-fork/bugs/" target="_blank"><em>XTrackCAD</em> Fork Project Site</a>.
+</p>
+<p>
+<strong>Be sure to provide the three basic elements of a bug report:</strong> What you were doing at the time the bug occurred, what you expected to happen and what actually happened. This detail will help developers replicate the error, find and correct the offending code.
+</p>
+<dl><dt>
+<strong>A Sample Bug Report Follows;</strong>
+</dt>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+After completing installation of <em>XTrackCAD</em> on a Dell PC with 1024 MB of memory running Windows 7, the following error occurred when attempting to edit a Text Label;
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<code>Notice: allocateButt: Can't find 13. Do you want to save the layout?</code>
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+Selecting either "Yes" or "No" results in a Windows error and <em>XTrackCAD</em> closes.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+The error can be replicated by opening the file named cascade.xtc. Set the magnification at 4:1. Attempting to move the text label named "Granville Island" located at the approximate grid coordinates of x=8", y=4' 5". Selecting the label causes the error to occur.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+The error is repeatable with other files contain text labels.
+</dd>
+</dl>
+<p>
+<strong>Always search the bug database first.</strong> Advice so good, we'll repeat it twice. Always search the bug database first. The odds are good that if you've found a problem, someone else found it too. If you spend a few minutes of your time making sure that you're not filing a duplicate bug, that's a few more minutes someone can spend helping to fix that bug rather than sorting out duplicate bug reports.
+</p>
+<p>
+<strong>If you don't understand an error message, ask for help.</strong> Don't report an error message you don't understand as a bug. There are a lot of places you can ask for help in understanding what is going on before you can claim that an error message you do not understand is a bug. (Once you've understood the error message and have a good suggestion for a way to make the error message clearer, you might consider reporting it as a <a href="https://sourceforge.net/p/xtrkcad-fork/feature-requests/" target="_blank"><em>XTrackCAD</em> Feature Request</a>).
+</p>
+<p>
+<strong>Please be brief, but don't leave any important details out.</strong> This is a fine line to walk. But there are some general guidelines:
+</p>
+<p>
+Remember the three basics: what you were doing, what you expected to happen, and what happened.
+</p>
+<p>
+If you can recreate the problem the <strong>Macro&gt;Record</strong> command can be used to record what happened. Try to isolate the problem by creating a minimal layout and recording as few commands as possible.
+</p>
+<p>
+<strong>Don't report bugs about old versions.</strong> Every time a new version of <em>XTrackCAD</em> is released, many enhancements are added and known bugs are fixed. If you're using a version of <em>XTrackCAD</em> that's more than two revisions older than the latest version, you should upgrade to the latest version to make sure the bug you are experiencing still exists. (It's not a bad idea to upgrade even if your version is only a version behind the most current one.)
+</p>
+<p>
+<strong>Only report one problem in each bug report.</strong> If you encounter two or more bugs that don't appear to be related create a separate bug report for each one. This makes the task of managing work assignments easier and may result in a quicker fix for the problem.

+Circle tracks are useful for fitting curves into corners and other tight places. They're also handy when establishing an initial layout and finding out "what will fit".
+</p>
+<p>
+You can join to and from circles, after which they become curved tracks.

+If the Snap Grid (<a href="cmdGrid.html#cmdGrid">Section 2.12.2</a>) is enabled then the endpoints will be constrained to the grid if they are not snapped to another object. <code>Shift</code> ensures that other objects will be ignored.

+</p>
+<p>
+<img src="png.d/cornuendanchor.png">
+</p>
+<p>
+The anchor is only drawn for Cornu ends that are not joined to existing tracks and it shows the position, direction and radius of the track, and has anchors for altering these properties. When the Cornu is joined to a track, it uses the properties of the end of that track instead. Anchor point handles are drawn outside the end of the Cornu track to allow track-pins to be edited on the track itself. <code>Left-Click</code> to place the second Endpoint either on a track endpoint or not. <code>Left-Drag</code> sets the second end angle like the first for unconnected end-points.
+</p>
+<p>
+Complete the Curve by pressing <code>Enter</code>, or Reject it with <code>Esc</code>.
+</p>
+<p>
+The radius and angle of the selected open Cornu end can also be set with text entry boxes in the Status Bar.
+</p>
+<p>
+When either endpoint is being moved it will "Snap" to an open track endpoint of the tracks underneath the cursor unless <code>Shift</code> is held. You can then only move the endpoint along that track if it is splitable, or in an extension of it. After the new track is completed, it will be connected to these existing tracks.
+</p>
+<p>
+Cornu Track Pins are further explained in <a href="joinCornu.html#joinCornu">Section 2.2.7.4</a> - they constrain the Cornu curve to smoothly pass through thier position as well as satisfying the end conditions. You can place them by clicking on the Cornu and select, <em>Drag</em> to move them around or hit <em>Delete</em> to remove them.
+</p>
+<p>
+If the end is not connected, an anchor will enable the end-angle and radius to be set by dragging. Initially the end radius is set to be zero and the angle will be picked to create a smooth curve given the end angle. Altering the end angle with the anchor resets the radius to zero.

+<p>
+<img src="png.d/bhndldto.png">
+</p>
+<p>
+Hand-laid turnouts are created by specifying 3 values:
+</p>
+<ul><li>
+Position of <em>Frog</em>
+</li>
+<li>
+Angle of <em>Frog</em> (the frog number)
+</li>
+<li>
+Position of <em>Points</em>
+</li>
+</ul>
+<p>
+First select the position for the Frog (<a href="generalTerms.html#generalTerms">Section B.2</a>) on an existing track and then <em>Drag</em> away to specify the angle of the <em>Frog</em>. The angle in degrees and equivalent frog number is displayed on the status bar. When you release, the line indicating the angle jumps to one side of the track to show you the center line of the new leg of the turnout.
+</p>
+<p>
+Next <code>Left-Click</code> and <code>Left-Drag</code> to position the Points (<a href="generalTerms.html#generalTerms">Section B.2</a>) for the turnout. As you <code>Left-Drag</code>, tracks will be drawn showing the turnout. When you release the turnout is created.
+</p>
+<p>
+You cannot place the <em>Frog</em> or <em>Points</em> on a turnout, circle or helix. However, you can create overlapping Hand-laid Turnouts.
+</p>
+<p>
+There are constraints on where you can place the <em>Points</em> in relation to the <em>Frog</em>. You cannot place the <em>Points</em> too close the <em>Frog</em>. When placing Hand-laid Turnout on a curved track you may get unexpected results, especially when placing the <em>Points</em> a long way from the <em>Frog</em>. Try changing the <em>Frog</em> angle to get different results.
+</p>
+<p>
+Note: the drawing is an approximation to show the location of the <em>Points</em> and <em>Frog</em>. The piece of track considered (by <em>XTrackCAD</em>) to be a Hand-laid Turnout is a short section of track located at the <em>Points</em> and extending toward the <em>Frogs</em>. Other track segments are created between the <em>Points</em> and <em>Frog</em> and a short straight segment is drawn after the <em>Frog</em>. These other segments are independent of the turnout and can be removed or modified, although this is probably not a good idea.

+<h1><a name="cmdHelix"></a>2.1.4 <a name="i0"></a>Helix Track</h1>
+<p>
+<img src="png.d/bhelix.png">
+</p>
+<p>
+A helix track is used to change the elevation of track in a restricted space. A helix is drawn as a circle of track, but in 3 dimensions it would resemble a cork screw or the pattern of threads on a bolt.
+</p>
+<p>
+<img src="png.d/ahelix.png">
+</p>
+<p>
+A helix is defined by the number of <em>Turns</em> and <em>Radius</em>.
+</p>
+<p>
+The helix dialog allows you to calculate these values based other parameters such as the <em>Elevation Difference</em>, <em>Grade</em>, <em>Vertical Angular Separation</em>. <em>Angular Separation</em> is the difference in degrees between tracks entering and exiting the helix. Changing any of these values effects the other values. For example, increasing the <em>Radius</em> decreases the <em>Grade</em>. Changing the number of <em>Turns</em> affects the <em>Vertical Separation</em> and either the <em>Radius</em> or <em>Grade</em>.
+</p>
+<p>
+In the case where different parameters could be affected (for instance changing <em>Elevation Difference</em> can affect <em>Radius</em> or <em>Grade</em>) the last parameter you changed will be preserved. If you set the <em>Grade</em> and then <em>Elevation Difference</em> then the <em>Radius</em> will be adjusted.
+</p>
+<p>
+Changing <em>Vertical Separation</em> affects <em>Turns</em> which must be an integer value (no fractions), and this in turn affects the <em>Vertical Separation</em>. When you set <em>Vertical Separation</em> you are specifying the minimum separation which is adjusted upwards to the actual value.
+</p>
+<p>
+The separation is rail-head to rail-head and you need to ensure this is enough to provide clearance when track, sleepers, ballast, baseboard/benchwork is included.
+</p>
+<p>
+Note: only the <em>Radius</em> and <em>Turns</em> are used when creating the helix. After joining the helix to other tracks, you will want to establish the heights of the endpoints at each end of the helix. You can use the Elevation (<a href="cmdElevation.html#cmdElevation">Section 2.2.5</a>) command to do this.
+</p>
+<p>
+A helix is placed the same way as a Circle Track (<a href="cmdCircle.html#cmdCircle">Section 2.1.1</a>) with the addition that you specify the number of turns as well the as the radius of the helix. Then the helix is dragged into position on the layout.
+</p>
+<p>
+You can join to a helix in the same way you join to a circle. However, once joined the helix is still drawn as a circle of track.
+</p>
+<p>
+A label for the helix is drawn at it's the center. If the elevations are set (either by a Defined Elevation point or connecting to a Defined Elevation point) for the two ends of the helix then the label contains the computed grade and vertical separation between layers as well as the number of turns and total length. The label can be moved or turned off by the Move Label (<a href="cmdMoveLabel.html#cmdMoveLabel">Section 2.2.10</a>) command.

+The <strong>Parallel Separation</strong> control (Visible in the Status Bar) displays the intended separation between parallel tracks/line. This value can be changed before selecting a track. The value must be greater than 0.0 if the gauges are equal.
+</p>
+<ul><li>
+If the gauges are equal, a value of 0.0 means that the rail of the second track is overlaid on the first to simulate dual guage track. The railside that the new track "shares" is set by which side of center the cursor is on when released. The new track will have NoTies set on.
+</li>
+<li>
+The seperation can be automatically increased using the <strong>Radius Factor</strong> value. If this is set to 0.0 (default) the seperation value will be used regardless of radius. If the value is set to 1.0, the seperation will be increased by a scaled 2864 inches per inch of curvature of the paralled track - this is in accordance with North American prototype practice. Other values of Radius Factor will alter by an equivalent percentage. For example, 0.5 would use 50% of this increase.

+A switchmotor is created by selecting <strong>Create SwitchMotor</strong> from either the Add menu <a href="cmdAdd.html#cmdAdd">Section 3.3.1</a> or from the switchmotor menu on the hotbar and then clicking on a turnout. A switchmotor gets a name and three scripts. The name is only used for identification and the three scripts are used by the layout control software. The three scripts are for throwing the turnout to its "normal" position, throwing the turnout to its "reverse" position, and a script to read a point position sensor. These scripts could be code snippets or they could be addresses of I/O devices, etc.
+</p>
+<p>
+<img src="png.d/switchmotor.png">
+</p>
+<p>
+The create switchmotor dialog has spaces for four text strings. One is the name and the other three are scripts for Normal, Reverse, and Point Sense. The name identifies the switchmotor and the scripts are information used by the layout control software to throw the turnout to the normal position, throw the turnout to the reverse position, and sense the point position. The scripts could be code snippets or I/O device address information, etc.

+The create/edit signal dialog has spaces for the name of the signal, its location and orientation, the number of heads (1, 2, or 3), and a list of aspects. Each aspect has a name and a script. The name could be a rule book name (Clear, Aproach, Stop, etc.) or the actual color(s) displayed (green, yellow, red, etc.). The script is just some information for the layout control software to actually effect the display of the aspect -- this could be the LCC event id to trigger the aspect or it could be a code snippet that causes the aspect to be displayed.

+<h1><a name="cmdConnect"></a>2.2.3 Connect Tracks</h1>
+<p>
+<img src="png.d/bconnect.png">
+</p>
+<p>
+This command is frequently used with <a name="i0"></a><em>Sectional Track</em>. But it can be useful to reattach ordinary track which has become disconected or split.
+</p>
+<p>
+When in this connect, ends of tracks that can be selected are highlighted with a blue arrow. With <em>Shift</em> added, ends that can be tighten are highlighted with a blue "X".
+</p>
+<p>
+There are three modes,
+</p>
+<p>
+
+</p>
+<ul><li>
+a <strong>Left</strong> click on a track near a disconnected end-point followed by a second on a close-by disconnected end-point on another track will try to join two tracks
+</li>
+<li>
+a <strong>Shift-Left</strong> click on a connected track will "Tighten Tracks" moving other tracks connected to this track to reduce any small distance or angle differences
+</li>
+<li>
+Selecting a set of tracks followed by a <em>"S" key</em> or using the Context menu will prompt for confirmation that all selected tracks with unconnected endpoints should be joined to nearby selected track at an unconnected end point. This mode allows for an entire layout to be reconnected after a Select-All.
+</li>
+</ul>
+<p>
+<strong>Notes for two track mode:</strong> Occasionally pieces of sectional track do not line up exactly, especially when creating figure-8's or passing sidings. When laying out the actual track you can compensate for this by adjusting the individual tracks to provide a bit of slack. This command simulates that process.
+</p>
+<p>
+Click on the endpoint of each track you're trying to connect. XtrkCAD will move the tracks slightly in an attempt to overcome the gap. If the gap is too large, the connection will fail. If this occurs, try using other track pieces in your layout.
+</p>
+<p>
+<em>XTrackCAD</em> adjusts the positions of tracks connected to the tracks up to a track with more than two connections. See the Demo for details.
+</p>
+<p>
+If one (or both) the selected tracks is an adjustable section (such as Kato's Adjustable Track #20-050) then the length of the track is changed to fill the gap.
+</p>
+<p>
+You can undo the effect of the <strong>Connect</strong> command by splitting (<a href="splitDisconnect.html#splitDisconnect">Section 2.2.17.2</a>) the track to disconnect it then using the <em>Shift+Left-Click</em> <strong>Connect</strong> command on the unconnected endpoints to tighten connections between the tracks.

+<p>
+The <strong>Elevation</strong> command changes the elevation of track endpoints. After opening this dialog, The Message Bar will show the computed elevation at the cursor. There will be an open blue circle if an endpoint will be selected with <strong>Left-Click</strong>. You click on the respective endpoint to set its elevation properties.
+</p>
+<p>
+The endpoint which you are working on is indicated with a big red dot. Note that when an endpoint is selected, the Elevation Window will have focus. To select a different endpoint without closing this window, two clicks (or a double click) will be needed. The first click restores focus to the main window, the second selects the point.
+</p>
+<p>
+If you add <strong>Shift</strong> as you move the cursor before clicking you will see a blue bar when it is over a track if a <strong>Shift+Left-Click</strong> will split the Track at that point (which will give you the opportunity to specify an elevation).
+</p>
+<p>
+Adding <strong>Ctrl</strong> allows you to <strong>Ctrl+Left-Click</strong> to Select and <strong>Left-Drag</strong> to move existing Elevation Labels if the option is set for them to be displayed and the Zoom level is adequate, Only "Defined" and "Station" endpoint labels can be moved.
+</p>
+<p>
+If you add <strong>Alt</strong>, while moving around the layout close to tracks will show you the elevation at the point indicated by a blue closed dot.
+</p>
+<p>
+With <strong>Alt</strong> held, if you hover over a point close to where two unconnected tracks pass over one another, a blue square will be drawn and the Message Bar will show the two elevations and the Clearance between them.
+</p>
+<p>
+Clicking with <strong>Shift</strong> at this point will split the track, allowing the elevation to be adjusted to provide adequate clearance.
+</p>
+<p>
+<img src="png.d/celev.png">
+</p>
+<p>
+An endpoint can have one of several elevation types:
+</p>
+<p>
+
+</p>
+<ul><li>
+<strong>None</strong> - no elevation control defined. This is the default state and the elevation will be computed. It will be shown if the Display Option <a href="cmdDisplay.html#cmdDisplay">Section 2.10.3</a> <strong>EndPt Elevations</strong> setting is on.
+</li>
+<li>
+<strong>Defined</strong> - the defined elevation is set to a specified height. The elevation will be shown.
+</li>
+<li>
+<strong>Hidden</strong> - a defined elevation like <strong>Defined</strong> but not displayed on the layout.
+</li>
+<li>
+<strong>Computed</strong> - height is calculated and displayed even if the Display Option <a href="cmdDisplay.html#cmdDisplay">Section 2.10.3</a> <em>EndPt Elevations</em> is on.
+</li>
+<li>
+<strong>Grade</strong> - grade is based on height of closest neighbors and displayed.
+</li>
+<li>
+<strong>Ignored</strong> - endpoint is not considered in computations. This breaks the flow of the elevation influence from one side to the other, resulting in an elevation that is not dependent on the connected track but on the other connected tracks. A common use would be to ensure a mainline dictates the elevation of the start of a branch.
+</li>
+<li>
+<strong>Station</strong> - assigns a name to the endpoint.
+</li>
+</ul>
+<p>
+<strong>Note:</strong> Only one of these attributes can be assigned to an endpoint at a time. For example, an endpoint can not be defined as a Grade and a Station at the same time.
+</p>
+<p>
+When an endpoint is selected on the layout by <em>Left-Click</em>, it is highlighted by a large red dot and its elevation type and values are displayed in the dialog.
+</p>
+<p>
+Additionally, <strong>Defined Elevation</strong> endpoints are indicated on the layout by gold colored dots. <strong>Ignored Elevation</strong> endpoints are indicated by blue colored dots.
+</p>
+<p>
+The grade at the specified endpoint is displayed next to the <strong>Grade</strong> radio button. For <em>Defined Elevation</em> endpoints, the grade on each side of the endpoint is displayed.
+</p>
+<p>
+<strong>Defined Elevation</strong> endpoints are used to specify fixed heights of track endpoints. Typically, this would be where a grade changes or where clearances must be maintained. <strong>Computed</strong> Elevations and <strong>Grade</strong> markers can place between <strong>Defined Elevation</strong> endpoints. These values are not entered directly but are computed dynamically based on <strong>Defined Elevations</strong> of connected tracks. This allows labeling of elevations at intermediate endpoints without having the enter specific values. <strong>Computed</strong> markers can also placed between a <strong>Defined Elevation</strong> point and the end of a track.
+</p>
+<p>
+<strong>Stations</strong> are used to provide information for the Profile (<a href="cmdProfile.html#cmdProfile">Section 2.2.12</a>) command.
+</p>
+<p>
+All <strong>Elevation</strong> labels (including <strong>Grade</strong> and <strong>Station</strong>) are drawn on the layout in outlined boxes. These may be moved by the <strong>Move Description</strong> (<a href="cmdMoveLabel.html#cmdMoveLabel">Section 2.2.10</a>) command. In addition, <strong>Grade</strong> labels have an arrow indicating the upwards direction.

+<p>
+Elevations of Tracks are computed in following steps. The colors listed in each step are used as the background color of the Track Elevation Markers (if they are enabled (<a href="cmdDisplay.html#cmdDisplay">Section 2.10.3</a>)).
+</p>
+<ul><li>
+The Shortest Paths between all <em>Defined Elevations</em> are computed. A Path stops at <strong>Ignored</strong> or <em>Defined</em> endpoints. The Elevation of any Turnouts on these Paths with more than two connections are computed as the average Elevation inversely weighted by distance along the tracks to the <em>Defined Elevation</em> points (<em>Blue</em>).
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+The Elevation of any other tracks on the Shortest Paths are computed based on the distance along the tracks from the Turnouts computed in the first step and/or the <em>Defined Elevation</em> points (<em>Purple</em>).
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+The Elevation of any remaining tracks is computed based on the average Elevation of the tracks found in the first two steps that they are (directly or indirectly) connected to, inversely weighted by geometric distance (<em>Gold</em>).
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+Any remaining tracks are not connected to a <em>Defined Elevation</em> and do not have an Elevation.
+</li>
+</ul>
+<p>
+The elevation computation is performed incrementally every time the layout is changed to keep all elevations in sync. The performance of the computation is affected by the placement of the <em>Defined Elevation</em> endpoints and the number of Paths between them. Place the <em>Defined Elevations</em> at points where tracks begin to branch (such as the throat of a yard or at the ends of a siding). Also, use <em>Defined Elevations</em> or <em>Ignore Elevations</em> to break the layout into areas so recomputation has fewer tracks and Paths to deal with.

+Certain turnouts, such as a Wye's, Three-Way or Crossings are symmetrical and thus titles for this type of objects are not changed. If a title change is necessary the currently loaded <strong>Parameter Files</strong> (<a href="cmdPrmfile.html#cmdPrmfile">Section 2.5.7</a>) are searched for a turnout that matches the flipped turnout. If a match is not found, the turnout's title is prefixed with <strong>Flipped</strong>. The <strong>Properties</strong> (<a href="cmdDescribe.html#cmdDescribe">Section 2.2.13</a>) command be used to change the title of such turnouts.

+If the track appears in red, it means <em>XTrackCAD</em> can't determine how to connect the first track with the second. If this occurs, while holding the left mouse button, drag the mouse back toward the first track until the connecting track appears in black. If the connecting track remains red, drag the mouse in the opposite direction until the connecting track turns black. Once the connecting track turns black, release the mouse button to finalize the <em>Join</em> command.

+Throughout the above, the exact shape of the curve can be adjust by dragging the mouse around while keeping the left mouse button held down.
+</p>
+<p>
+Sometimes, no matter where you drag the mouse, the curve stays red and the tracks cannot be connected. This means the resulting curve is tighter than the minimum track radius set in the <em>Preferences dialog</em> (<a href="cmdPref.html#cmdPref">Section 2.10.7</a>). If desired, this setting can be adjusted from the <em>Preferences dialog</em> using the <strong>Options&gt;Preferences</strong> menu selection to raise the dialog. If changing the minimum track radius is not a desired option then it will be necessary to relocate one of the tracks that you're attempting to join.
+</p>
+<p>
+You may also find that <em>XTrackCAD</em> will not create the connecting curve in the exact shape you want. If this happens it may be necessary to either move one of the end points or draw a partial curve (or straight) and try again.
+</p>
+<p>
+If enabled, Easements (<a href="cmdEasement.html#cmdEasement">Section 2.10.4</a>) will be automatically generated between tracks of differing radii. When using easements, there is a minimum radius as specified in the <em>Easement</em> dialog. It's not possible to join tracks with less then this radius and the connecting track's radius must be greater than the minimum radius.
+</p>
+<p>
+If any errors occur while joining tracks (such as moving beyond the end of a track or using a curve with a radius smaller than the Easement radius), then the joint track will be drawn in Red (The default colour of Exception Track errors. See <a href="cmdRgbcolor.html#cmdRgbcolor">Section 2.10.1</a> for detail). This colouring serves as visual indication for a connecting track that doesn't meet minimum specified parameters (<a href="cmdPref.html#cmdPref">Section 2.10.7</a>).
+</p>
+<p>
+Any tracks created during the <strong>Join</strong> command will have the following properties inherited from the first track: selected state, hidden state, scale, track gauge and Layer.
+</p>
+<p>
+A join can be made to or from a circle (<a href="cmdCircle.html#cmdCircle">Section 2.1.1</a>) of track. Joining a track with a circle will cause the circle to be converted into a curved track.

+</p>
+<p>
+A Cornu is a form of curve that uses a mathematical approach to creating a curve between two sets of end conditions.
+</p>
+<p>
+The curve is designed to change curvature linearly along its length - which is the characteristic of a railway easement because it minimizes sudden changes in acceleration towards the center of curvature.
+</p>
+<p>
+The conditions used at each end are the radius, angle and position.
+</p>
+<p>
+Cornus can have added constraints in the form of track "pins" that force the curve to smoothly pass through that point while still respecting the end conditions.
+</p>
+<p>
+Cornus can be used in XtrackCAD to both Join tracks smoothly and form smooth curves that are not joined to other tracks.
+</p>
+<p>
+Because Cornu are mathematically generated, they can also be regenerated at will and so Cornu Joins have the unique characteristic in XTrackCAD that they remain connected even if the tracks at the ends are moved or even change shape.
+</p>
+<p>
+Cornu Joins will use whatever space is available - that is their "tightness" (rate of change of curvature) is variable and dynamic. The minimum radius is calculated and will show as an exception, but the acceptable rate of change of curvature is the choice of the designer.
+</p>
+<p>
+It is not always the case that the Cornu will be the most efficient way to get from A to B - because of its shape it will be the smoothest. If you want to bias the result, you can add TrackPins (<a href="cornuTrackPins.html#cornuTrackPins">Section 2.2.7.5</a>).

+<h1><a name="cornuTrackPins"></a>2.2.7.5 Cornu Track Pins</h1>
+<p>
+XTrackCAD Cornu can have "track pins" added that constrain the track to pass through those points in addition to meeting the end-conditions. This allows the track to be skewed or slewed around obstacles, or to suit some other constraint.
+</p>
+<p>
+The pins can be added when Cornus are created <a href="cmdCornu.html#cmdCornu">Section 2.1.2.6</a> or during <a href="cmdModify.html#cmdModify">Section 2.2.8</a> after clicking on the track. They can be selected and then <code>Left-Drag</code> dragged to alter the curve shape or deleted with <code>Delete</code>.
+</p>
+<p>
+When a Cornu Track with pins is saved, it is split into two Cornu joined at the pin. If a Cornu that is joined to another Cornu is Modified with <a href="cmdModify.html#cmdModify">Section 2.2.8</a>, the joints are rendered as Pins and the Modify is done for one continuous Cornu.
+</p>
+<p>
+
+</p>
+<ol><li>
+First, ensure that the Easement type option is set to Cornu - see <a href="cmdEasement.html#cmdEasement">section 2.10.4</a>

+</p>
+<p>
+Before a track is selected for Modify, a dynamic blue anchor will show which track the command will take effect on if the cursor is close enough to a modifyable track or object. Arrows are shown to indicate if the track can be extended or trimmed and also if its radius can be modified if Shift is depressed as the cursor is moved over the track.

+<h1><a name="chgDraw"></a>2.2.8.7 Modifying Draw Elements</h1>
+<p>
+Draw elements have blue handles that show how they can be modified. They also have text entry boxes that allow precise entry of parameters. These values become active when a <em>Tab</em> is entered, or the cursor is moved out of the text box.
+</p>
+<p>
+There is a context menu accessed via <em>Right-Click</em> for Draw Objects that can change the edit mode from the initial "Points Mode" to "Origin Mode" where <em>Click</em> sets the position of the drawn object's origin - which will cause subsequent rotations using <a href="cmdModify.html#cmdModify">Section 2.2.8</a> or <a href="cmdDescribe.html#cmdDescribe">Section 2.2.13</a> to be centered about that point.
+</p>
+<p>
+The context menu can be used to go back to Points Mode, or to set the origin to one of a number of defined points. There are text shortcuts - "o" for Origin Mode and "p" for Points Mode.
+</p>
+<p>
+In Origin Mode, the context menu allows the origin to be set to be -
+</p>
+<dl><dd>
+<em>Absolute</em> (shortcut "0") with the origin at the layout origin or
+</dd>
+<dd>
+<em>Relative</em> by dragging the origin to a point, or snapping to the position of the first 4 corner points (shortcut "1" through "4"), or to the middle/centroid of the shape (shortcut "m"). For a Polygon or Polyline the <em>Relative</em> origin can be snapped to a last selected node (shortcut "l").
+</dd>
+</dl>
+<p>
+
+</p>
+<p>
+In Points Mode,
+</p>
+<p>
+
+</p>
+<dl><dd>
+Lines have end points that can be dragged. <em>Shift-Drag</em> will snap the end to the end of a nearby Draw object, while <em>Ctrl+Drag</em> will snap to any point on a nearby Draw object. They have text entry boxes for length and angle.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+Curves have end points that work like Lines but also have a middle anchor that can be used to alter the curve radius. They have text box entry for Arc Length (in degrees) and Radius.
+</dd>

+When a Polygon or a PolyLine is modified, open blue circle anchors show the position of its "nodes", these are selected with <strong>Left-Click</strong> and are shown as filled circles.
+</p>
+<ul><li>
+<strong>Left-Drag</strong> of a selected node of a <em>PolyLine</em> or <em>Polygon</em> moves that node to a new position, and if moved close enough to a neighboring node will merge the two nodes and delete the edge between them.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+<strong>Delete</strong> or <strong>Backspace</strong> will remove a selected node.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+<strong>Left-Clicking</strong> on an edge will create a new node that can be dragged to position it.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+Multiple points can be selected using <strong>Shift+Left-Click</strong>. If these are then <strong>Left-Drag</strong>ed all the selected points move together, preserving relative position.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+There is a context menu that has controls for a selected point. It has options to alter the node into a rounded node (shortcut "r") or a smooth node (shortcut "s"). To turn it back into a sharp (vertex) node (shortcut "v").
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+If <em>Shift</em> is held down while dragging, the relative angle for the first selected point to its predecessor point will be locked to a multiple of 90 degrees.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+When a node or nodes is/are selected, text entry boxes for length and relative angle (the deviation angle from the direction of preceeding side) can be used to fine-tune the position of the first node in the sequence. A arc indicator identifies the angle in question.
+</li>
+</ul>
+<p>
+
+</p>
+<p>
+If no nodes are selected,
+</p>
+<p>
+
+</p>
+<ul><li>
+A context menu can be used to close a polyline into a polygon (shortcut "g") or open it (shortcut "l") into a non-filled polygon between its last and first nodes.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+A unfilled polygon can also be filled (shortcut "f") or a filled one emptied (shortcut "u").
+</li>
+</ul>
+<p>
+
+</p>
+<p>
+Notes
+</p>
+<p>
+
+</p>
+<dl><dd>
+A selected Polygon or Polyline node can only be deleted if there are at least three nodes left. It can only be round or smooth if long as it isn't an end node of a Polyline.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+Smoothed nodes implement a short Bezier curve that goes from halfway along the line of to the next node and which has a control arm that ends at the node. These are typically of most use to fine-tune a series of nodes that simulate a complex curve.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+Rounded nodes start at a distance that is half the shorter of the lines from the last node and to the next node and has control arms that extend to the half-way point to the node. This produces an arc whose radius is determined by the distance of the closet node. By manipulating the nearest node (for example, by adding a point) the radius at the node can be controlled.

+</p>
+<p>
+This command is used to move selected (<a href="cmdSelect.html#cmdSelect">Section 2.2.16</a>) objects around the layout.
+</p>
+<p>
+The <strong>Move</strong> command can be invoked using the <strong>Change&gt;Move</strong> menu item or the <strong>Move</strong> button and from the menu that's raised by a <em>Right-Click</em> over the <strong>Main Canvas</strong> or by the <em>Shift+Left+Drag</em> command when in <strong>Select</strong> mode.
+</p>
+<p>
+Successful use of this command requires selection of the object(s) to be moved before attempting to move it. An object is selected by using the <em>Left-Click</em> command. A group of connected objects can be selected using the <em>Shift+Left-Click</em> command.
+</p>
+<p>
+A move can be achieved using one of the following methods;
+</p>
+<p>
+
+</p>
+<dl><dd>
+<em>Left+Drag</em> using the mouse. See <a href="moveByMouse.html#moveByMouse">Section 2.2.9.1</a> for detail.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+Selecting fixed or specified amounts of translation in the X and Y directions using a <em>Right-Click</em> menu. See <a href="moveByMenu.html#moveByMenu">Section 2.2.9.2</a> for detail.
+</dd>
+</dl>
+<p>
+
+</p>
+<p>
+During a Move of tracks, and <strong>MagneticSnap</strong> (<a href="cmdMagneticSnap.html#cmdMagneticSnap">Section 2.12.1</a>) is enabled, if one of the end-points of the selected objects is close to an open end of a unselected point, two anchors (an open an closed blue ball) will appear. This indicates that the two points will auto-join and that all the moved tracks will align to the unselected point if the Move is stopped. This behaviour can be suppressed with <em>Alt</em>. If <strong>MagneticSnap</strong> is disabled, the alignment will only occur if <em>Alt</em> is pressed.
+</p>
+<hr>
+<p>
+<strong>Note:</strong> If the moved track is connected but the track it is connect to is not moved, it will be disconnected, unless that track or the last selected track is a Cornu, in which case the Cornu concenred will be modified (if possible) to remain connected.
+</p>
+<p>
+<strong>Note:</strong> Cornu tracks connected to a turntable will be modified if it is moved or rotated. They remain connected at the point on the radius where they started, so it may be desireable to delete and redraw them if the rotation is large.

+Alternatively, <em>Shift+Ctrl+Arrow</em> can be used to micro-move the selected object(s). The amount micro-moved is dependent on the zoom in use. To move by smaller increments, zoom in further. My moving to macro-zoom modes extremely fine adjustments can be made.

+This command is used to move Elevation, Grade, or Station (<a href="cmdElevation.html#cmdElevation">Section 2.2.5</a>), and to enable/disable and move Straight Track (<a href="cmdStraight.html#cmdStraight">Section 2.1.6</a>), Curved Track (<a href="cmdCurve.html#cmdCurve">Section 2.1.2</a>), Bezier (<a href="cmdBezier.html#cmdBezier">Section 2.1.2.5</a>, Cornu (<a href="cmdCornu.html#cmdCornu">Section 2.1.2.6</a>), Joint (<a href="cmdJoin.html#cmdJoin">Section 2.2.7</a>), Helix (<a href="cmdHelix.html#cmdHelix">Section 2.1.4</a>) and Structure or Turnout (<a href="cmdHotBar.html#cmdHotBar">Section 2.7</a>) Labels.
+</p>
+<p>
+The <strong>Move Description</strong> command can be invoked using the <strong>Change&gt;Move Description</strong> menu item or the <strong>Move Description</strong> button.
+</p>
+<p>
+Click the <strong>Move Description</strong> button to activate the <strong>Move Description</strong> command. As the cursor passes close to an object that can display a label it will be highlighted. A dark blue indicates a label that has "Show Description" set on, a teal color means it is set to hide.
+</p>
+<p>
+Use <em>Left+Drag</em> to move the label to a new position and unhide if hidden. Once moved, the label becomes fixed in a position relative to the object. Subsequent moves of that object will cause the label to move as well.
+</p>
+<p>
+This operation can also be invoked by <em>Ctrl+Left+Drag</em> when in Select command (<a href="cmdSelect.html#cmdSelect">Section 2.2.16</a>).
+</p>
+<p>
+Note that labels need to be visible in the Display menu and the layout needs to be zoomed in enough to show labels for them to be moved.
+</p>
+<p>
+There are keys that control the display of description when hovering over a description or a track.
+</p>
+<ul><li>
+The letter "<strong>s</strong>" when hovering over a track will show the hidden description - the teal highlight will show which tracks can have descriptions.
+</li>
+<li>
+The letter "<strong>h</strong>", when hovering over the track or description, can be used to hide display of individual Curved Track, Bezier Track, Cornu, Helix, Joint or Turnout Labels.
+</li>
+<li>
+The letter "<strong>d</strong>" will enable and disable a detailed description which is intended for tracklaying - it is a table of points and track angles that lie along the track path.
+</li>
+</ul>
+<p>
+Using these detailed values a curve can be constructed even for complex objects such as Bezier or Cornu.
+</p>
+<p>
+There is a <strong>Context Menu</strong> invoked with <em>Right-Click</em> or <em>Shift plus Right-Click</em> to Show/Hide individual descriptions as well as set the description to detailed.
+</p>
+<p>
+Labels can be moved by hovering the "hot spots" or over the attached track object. <em>Left-Drag</em> will reposition it. Elevation labels can be selected by hovering of thier centers or the end point they refer to. Note that end points with elevation mode "None" are not selectable.
+</p>
+<ul><li>
+Cornu, Bezier, Straight, Curve and Joint (Easement) Labels can be moved along the line between the end-points and also laterally.
+<p>
+
+</p>
+<ul><li>
+Cornu and Bezier Tracks show the "chord" length, its absolute angle, and the length of the track and the minimum radius. To help lay these variable radius curves out, the detailed description information about track centers and angles selected by <strong>'d'</strong> is suggested.
+</li>
+<li>
+Joint/Easement Tracks show the "chord" length and abslute angle and easement curve constructing values of Radius and Lengths. For laying out larger easmements, the detailed position and angle description selected by <strong>'d'</strong> may be useful.
+</li>
+<li>
+Straight Tracks show the length and the absolute angle. For laying out long straights, the detailed track center position and angle descriptions selected by <strong>'d'</strong> may be useful.
+</li>
+<li>
+Curved Tracks show the radius, chord length, deflection at the center from the chord and the angular length. For laying out curves, the detailed track center position and angle descriptions selected by <strong>'d'</strong> may be useful.
+</li>
+</ul>
+
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+Curve Track Labels can be moved so that the label is somewhere on a radial line from the center to a position within the arc. A Curve label shows the absolute angle of the chord, its length, the Curve Radius and the deflection from the chord at the center of it. This enables the curve to be laid out even if the center point of the arc is inaccesible. Note that the detailed description may also be helpful in this case.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+Compound (Structure and Turnout) Labels can be moved without restriction. They show the Object's Title information.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+Elevation points labels can be moved without restriction - they show the Grade, Elevation, or Station Name as appropriate.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+The detailed description setting is not preserved in the saved layout. It is designed for use when transferring a complex part of the plan to a real layout.
+</li>
+</ul>
+<p>
+Note - existing defined elevation labels can be moved, but controlling thier visbility is done with the <a href="cmdElevation.html#cmdElevation">Section 2.2.5</a> command.

+This command is used to move or resize the viewport using the mouse or keyboard. <em>Left+Drag</em> Pans the viewport up and down, left and right keping it within the boundaries of the layout. <em>Ctrl+Left-Drag</em> selects an area of the screen to zoom into. The <strong>"0"</strong> or <strong>"o"</strong> - key resets the display to the origin but leaves the zoom as is. Keys between <strong>1</strong> and <strong>9</strong> set the zoom to that zoom level. The <strong>"e"</strong> - key resets the origin to zero and the zooms to show the whole layout.

+<h1><a name="cmdProfile"></a>2.2.12 Profile</h1>
+<p>
+The <strong>Profile</strong> dialog draws a profile showing elevations, distances and grades for a path on the layout.
+</p>
+<p>
+<img src="png.d/dcprofile.png">
+</p>
+<p>
+Choose a path by using <em>Left-Click</em> on endpoints. As each endpoint is chosen, the path is extended via the shortest route. Selecting the end of the path trims the path back to a last <strong>Defined Elevation</strong> point (if any, otherwise the path is cleared).
+</p>
+<p>
+If no route is possible an error message is displayed. There are several reasons why this might happen:
+</p>
+<ul><li>
+The tracks are not connected. You can see this more easily if you turn on Display-&gt;Option-&gt;"Display Unconnected End Points" as Exception. You can also check this by using <em>Shift+Left-Click</em> on one track using the <strong>Select</strong> command (<a href="cmdSelect.html#cmdSelect">Section 2.2.16</a>). This selects all tracks connected (directly or indirectly). See if the other track is selected.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+One of the endpoints on the route is <strong>Ignored</strong> (<a href="cmdElevation.html#cmdElevation">Section 2.2.5</a>). Look for blue dots on the expected path when using the Profile or <strong>Elevation</strong> (<a href="cmdElevation.html#cmdElevation">Section 2.2.5</a>) commands.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+The only route connects to a section of track that is already on the path and is not the end of the path. Remove the end of the path until the connected track is not on the path.
+</li>
+</ul>
+<p>
+The path is drawn in the Profile Color (<a href="cmdRgbcolor.html#cmdRgbcolor">Section 2.10.1</a>) (default Purple) on the layout.
+</p>
+<p>
+If the shortest path is not what you want, you can choose endpoints that are closer to the end of the path. Also, you can <strong>Ignore</strong> (<a href="cmdElevation.html#cmdElevation">Section 2.2.5</a>) endpoints to prevent the path from choosing a route through that endpoint. Shift+Right-Click (<a href="cmdAcclKeys.html#cmdAcclKeys">Section 3.4</a>) displays a pop-up menu that allows you to change the specified endpoint to be a <strong>Defined</strong>, <strong>Ignored</strong> or <strong>None</strong> Elevation endpoint.
+</p>
+<p>
+Each <strong>Defined Elevation</strong> endpoint on the path is drawn as a Vertical bar, labeled with its height and distance from the beginning of the path.
+</p>
+<p>
+The <strong>Grade</strong> between points is displayed between the vertical bars. The <strong>Grade</strong> line is drawn in Blue if that portion of the path does not contain more than one Shortest Path between Defined Elevation endpoints. Otherwise it is drawn in Red, to indicate the grade is an average and the actual grade may vary for any particular track segment. See Computing Dynamic Elevation (<a href="computeElevations.html#computeElevations">Section 2.2.5.1</a>) for more details.
+</p>
+<p>
+<strong>Stations</strong> on the path are displayed along the bottom of the <strong>Profile</strong>.
+</p>
+<p>
+The heights of <strong>Defined Elevations</strong> can be changed by using <em>Left+Drag</em> on the profile window. As you <strong>Drag</strong>, the new elevation and grades to each side are displayed at the bottom of the profile dialog.
+</p>
+<p>
+The <strong>Change</strong> button makes the changes in the Profile dialog permanent.
+</p>
+<p>
+The <strong>Reset</strong> button deletes all changes since the last press of <strong>Change</strong> or the start of the dialog.
+</p>
+<p>
+The <strong>Clear</strong> button preserves elevation settings established along the current profile path, removes all profile points and leaves the <strong>Profile</strong> dialog open for selection of the next set of profile points. This function is useful when there's a need to view elevations along multiple profile paths.
+</p>
+<p>
+The <strong>Print</strong> button prints the dialog. The aspect ratio is preserved on the print-out. You will probably want to print in landscape format.
+</p>
+<p>
+The dialog can be closed with the 'X' button in the window's titlebar.

+<p>
+If the Object is a Line, Curve, Circle or Polygon object, and the rotation origin is non-zero, a large blue cross will show its position. If it is zero, the command starts with the <strong>Lock Origin</strong> field unticked and the <strong>Rotate By</strong> field greyed out.
+</p>
+<p>
+Some fields are used by multiple types of objects - these are listed below
+</p>
+<dl><dt>
+Line Width
+</dt>
+<dd>
+The width of the line for a line, curve or unfilled object can be set. 0 means a pixel width at all scales. Other values are the width of the line in scale units. If the value is negative, it is the absolute value of pixels wide at all scales.
+</dd>
+<dt>
+Pivot
+</dt>
+<dd>
+The Pivot control can be set to fix in place the start, or the middle or the end, and it applies to the Length, Line Angle and Angular Length controls. When these are changed the new dimensions are applied so as to keep the locked position in place.
+</dd>
+<dt>
+Rotation Origin
+</dt>
+<dd>
+By default the rotation origin is the Layout origin {0,0}. If the origin is not at the Layout origin, it will be displayed with a blue cross. When the origin is changed with the <strong>Lock</strong> off, the object is not moved. But if the origin is changed with the <strong>Lock</strong> on, the object will be moved as well. Enabling the <strong>Lock To Origin</strong> allows subsequent Rotations to be about the origin. This may be especially useful when using creating larger groups of Draw objects.
+</dd>
+<dt>
+Lock To Origin
+</dt>
+<dd>
+Locking to the rotation origin makes the distance between the First Point and the origin fixed. If this is set on, altering either the First Point or the Rotation Origin will move the both values. This value is initially set to locked if the Draw origin is non-zero when the <a href="cmdDescribe.html#cmdDescribe">Section 2.2.13</a> command is started but can be unset to allow repositioning of the Rotate Origin without moving the object in the layout. If the Rotate Origin is set to {0,0}, the Object has an <em>Absolute</em> origin.
+</dd>
+<dt>
+Rotate By
+</dt>
+<dd>
+Some Draw objects (Polygon, Polyline, Lines, Curves, Circles, Text) can be rotated about their rotation origin in Describe. In order to rotate them, the <strong>Lock To Origin</strong> must be enabled. After the rotation completes, the rotation angle will be set back to zero and all the points of the object will be adjusted to their absolute position in the layout. Negative values of rotation are counter-clockwise. Note that for Text objects, the Rotation also changes the <strong>Text Angle</strong>.
+</dd>
+<dt>
+Layer
+</dt>
+<dd>
+The layer of the object. The object can be moved between layers if the layer is not frozen. Only non-frozen layers are listed as options.
+</dd>
+<dt>
+Color
+</dt>
+<dd>
+The color of the line or the fill can be set

+<img src="png.d/brotate.png">
+</p>
+<p>
+This command is used to rotate selected (<a href="cmdSelect.html#cmdSelect">Section 2.2.16</a>) objects.
+</p>
+<p>
+The <strong>Rotate</strong> command can be invoked using the <strong>Change&gt;Rotate</strong> menu item, the <strong>Rotate</strong> button, the menu raised by a <em>Right-Click</em> over the <strong>Main Canvas</strong> or by the <em>Ctrl+Right-Drag</em> command when over a selected trak in <strong>Select</strong> mode.
+</p>
+<p>
+Successful use of this command requires selection of the object(s) to be rotated before attempting to rotate it. An object is selected by using the <em>Left-Click</em> command. A group of connected objects can be selected using the <em>Shift+Left-Click</em> command, or indivdual tracks added with <em>Ctrl+Left-Click</em>.
+</p>
+<p>
+A pop-up menu with commands controlling how objects move during the <strong>Rotate</strong> function can be activated by entering a <em>Shift+Right-Click</em> command while hovering over the <strong>Main Canvas</strong>.
+</p>
+<p>
+Note that a Rotate command for a Draw object does not use the Rotation Origin of that Object, even if has been defined as non-zero, instead it uses the position defined by the mouse or context command, and does not rotate the rotation origin.
+</p>
+<p>
+<img src="png.d/mrotatemove.png">
+</p>
+<p>
+Rotation can be achieved using one of the following methods;
+</p>
+<p>
+
+</p>
+<dl><dd>
+<em>Left+Drag</em> using the mouse. See <a href="rotateByMouse.html#rotateByMouse">Section 2.2.15.1</a> for detail.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+Selecting fixed or specified degrees of rotation using a <em>Right-Click</em> menu. See <a href="rotateByMenu.html#rotateByMenu">Section 2.2.15.2</a> for detail.
+</dd>

+<p>
+
+</p>

+Aligning the selected object with another object on the layout. See <a href="rotateByAlign.html#rotateByAlign">Section 2.2.15.3</a> for detail.
+</dd>
+</dl>
+<p>
+During Rotation of a track, if <strong>MagneticSnap</strong> (<a href="cmdMagneticSnap.html#cmdMagneticSnap">Section 2.12.1</a>) is enabled, if one of the end-points of the selected objects is close to an open end of a unselected point, two anchors (an open an closed blue ball) will appear. This indicates that the two points will auto-snap and the moved track will align to the unselected point if the Rotation is stopped. This does not happen if <em>Alt</em> is used. If <strong>MagneticSnap</strong> is disabled, the snap will only occur if <em>Alt</em> is held. Note that this also applies to <a href="cmdMove.html#cmdMove">Section 2.2.9</a>.

+This command is useful for placing tunnel portals or elevation points (<a href="cmdElevation.html#cmdElevation">Section 2.2.5</a>) at specific track locations.

+<p>
+Normally a turnout cannot be split however, if the <em>Shift</em> key is held when executing this command then the turnout can be <em>trim</em>med. <em>Trim</em>ming replaces the portion of track between the split point and the turnouts endpoint with flex-track. For turnouts with more than one set of points (<a href="generalTerms.html#generalTerms">Section B.2</a>), such as a slip switch or scissors crossover, a <em>trim</em> point cannot be selected between the <em>points</em> of the turnout.

+<h1><a name="cmdTrimDraw"></a>2.2.17.4 Trim a Draw Object using another Draw object</h1>
+<p>
+The <strong>Trim Draw</strong> command can be used to trim many draw objects (Straight Lines, Curved Lines, Circles, Polygons, PolyLines). Polygons and Circles are split into PolyLines and Curves.
+</p>
+<ol><li>
+First a Trimming object (draw object) is selected with <strong>Left-Click</strong>. Until the trim draw object is selected, a draw object under the cursor will be highlit in blue. Once it is selected it will be highlit in the current Select Color.
+</li>
+<li>
+Next the point of intersection between the trim object and an object to be trimmed is selected. Until a split point is selected, a suitable split point under the cursor will have a blue trim anchor that is a T shape aligned with the trimming object.
+</li>
+</ol>
+<p>
+The trim anchor base has an arm that indicates which side of the trimmed object will be deleted. A <strong>Left-Click</strong> will trim the object.
+</p>
+<p>
+
+</p>
+<p>
+If the trimmed object is a circle or a polygon, the result will be the same as a Split (<a href="cmdSplitDraw.html#cmdSplitDraw">Section 2.2.17.3</a>), a 355 degree circle and an open polyline with ends at the split will result.
+</p>
+<p>
+Once a trim has occured, the trimming object remains selected for another trim.
+</p>
+<p>
+To leave the command use the spacebar. If <em>Sticky</em> (<a href="cmdSticky.html#cmdSticky">Section 2.10.8</a>) is set for Split commands you will be able to select another trim object.

+Some objects will a natural rotation point within them. By setting the object origin to this point, subsequent rotation will be about that point and not the layout origin. This is referred to as a <em>Relative</em> origin and will be present if the origin is non-zero. When an object with a Relative is moved or rotated, the origin and angle are adjusted but the relative draw point values remain the same. If an object has a zero origin, it is called Absolute. If it is moved or rotated, the origin and angle remain zero, but all the obect point(s) are adjusted.
+</p>
+<p>
+You can choose to set the origin to make it Relative or put it back to Absolute (origin zero) during <a href="cmdDrawShapes.html#cmdDrawShapes">Section 2.3.6</a> or <a href="cmdModify.html#cmdModify">Section 2.2.8</a> or by using the <a href="cmdDescribe.html#cmdDescribe">Section 2.2.13</a> settings.
+</p>
+<p>
+As a practical matter, the object will appear identical until a subsequent rotation value is entered in the <a href="cmdDescribe.html#cmdDescribe">Section 2.2.13</a> window in both cases.
+</p>
+<p>
+In Origin Mode (entered using <code>'o'</code> or the Context Menu, there are certain shortcuts available -

+The <strong>Text</strong> command lets you enter a Text Draw object on the layout at the selected position. You can use the Tab key to format the text to fixed tab positions and CTRL+Enter to enter a newLine character.
+</p>
+<p>
+<img src="png.d/statustext.png">
+</p>
+<p>
+The font size can be changed by the Font Size drop list on the <strong>Status-bar</strong> (<a href="mainW.html#mainW">Section 3.1</a>). The font size is scaled along with everything else on the layout so text is always the same relative size as other layout objects.
+</p>
+<p>
+The color used can be selected by the Color icon on the <strong>Status-bar</strong> (<a href="mainW.html#mainW">Section 3.1</a>).
+</p>
+<p>
+The new text object can be "boxed" by having a line drawn around it using the Boxed tick-mark on the <strong>Status-bar</strong> (<a href="mainW.html#mainW">Section 3.1</a>).
+</p>
+<p>
+The position where text is to be placed on the layout is selected prior to text entry by <code>Left-Click</code>ing on the layout at the point where the text is to appear. Desired text is input after the position is selected. If necessary, the location can be changed once text entry begins by <code>Left-Click+Drag</code>ing the text to any desired postion on the layout.
+</p>
+<p>
+The <strong>Properties</strong> (<a href="cmdDescribe.html#cmdDescribe">Section 2.2.13</a>) command can be used to modify the contents, color and fontsize of existing <strong>Text</strong> objects and to set the boxes property.
+</p>
+<p>
+The new Text object is committed when another command is entered (or <em>Enter</em> is used if the Text command is Sticky).
+</p>
+<p>
+The font used for all Text objects can be selected by the <strong>Font Selection</strong> (<a href="fontSelW.html#fontSelW">Section 2.10.5</a>) dialog invoked by the <strong>Options&gt;Fonts</strong> menu item or by <code>Shift+Right-Click</code> (<a href="cmdAcclKeys.html#cmdAcclKeys">Section 3.4</a>).
+</p>
+<p>
+Note: loading fonts (or changing sizes) can take a noticeable amount of time.

+This menu item creates a bitmap file of the layout.
+</p>
+<p>
+<img src="png.d/bitmap.png">
+</p>
+<p>
+The <strong>Bitmap</strong> dialog specifies the style and size of the bitmap. The check-boxes (<strong>Layout Titles</strong>, <strong>Borders</strong>, <strong>Centerline of Track</strong> and <strong>Background Image</strong>) control whether the Layout Title (<a href="cmdLayout.html#cmdLayout">Section 2.10.6</a>), the borders or the track centerlines are printed on the bitmap. If a background image is used it will be printed if the option is set.
+</p>
+<p>
+The size of the bitmap is smaller if these are disabled.
+</p>
+<p>
+Printing the track centerlines (also seen when zoomed in 1:1) is useful when you later print the bitmap full size for laying out track.
+</p>
+<p>
+If the Snap Grid (<a href="cmdGrid.html#cmdGrid">Section 2.12.2</a>) is visible then it will be printed on the bitmap.
+</p>
+<p>
+The <strong>DPI</strong> control specifies the number of pixels per inch in the bitmap. Bitmaps must be less than 32,000 pixels in height or width. The upper value you can enter depends on the size of your trackplan. It is made sure that your bitmap does not exceed these limits. Larger values will result in a larger bitmap file.
+</p>
+<p>
+The bitmap width, height and approximate file size is indicated.
+</p>
+<p>
+Note: This command can create a very large file and consume a lot of memory and time.
+</p>
+<p>
+Pressing the <strong>OK</strong> button invokes a <strong>File Save</strong> dialog so you can choose the file name for the Bitmap.
+</p>
+<p>
+You can select to create JPEG or PNG files. As a rule of thumb JPEG results in smaller files when you use a backgound image, PNG does so for trackplans without an image background.

+Files in SVG format can be used for different purposes.
+</p>
+<ul><li>
+SVG files can be loaded into many drawing programs. This makes it possible to enhance and resize the image. Vector images have the advantage of allowing lossless resizing.
+</li>
+<li>
+Most modern browsers support SVG as an image format. So the resulting file can directly be used to publish your plan on the web. By adding a bit of Javascript, zooming and panning can be enabled. Appropiate scripts can easily be found using your favorite search engine. The generated SVG uses the layout description as a title that is shown by some browser. Also the drawing has an 'id' for manipulation by Javascript. This id is derived from the filename by removing all spaces and sticking the word 'id' in front. Eg exporting <code>stonega.xtc</code> the resulting id will be <code>idstonega</code>.

+<p>
+<img src="png.d/bparam.png">
+</p>
+<p>
+<em>Parameter Files</em> contain turnout, sectional track and structure definitions. Loaded Parameter Files are managed with the <strong>Parameter Files</strong> dialog.
+</p>
+<p>
+<img src="png.d/dprmfile.png">
+</p>
+<p>
+The dialog contains a list of parameter files. Each file is preceded by a color indicator. These indicators show whether a parameter file contains definitions that are usable in the current scale and gauge.
+</p>
+<p>
+<img src="png.d/greendot.png"> <img src="png.d/greenstar.png"> Definitions from this file are a perfect fit for the current layout options. The file has been loaded and will be visible in the <strong>HotBar</strong>. For track this means that gauge and scale of the track elements are identical to the layout settings. Prototype definitions (Scale "*") are always a perfect fit. Turnouts and Sectional Track must have the same gauge and usually the same scale unless the scale/gauge combination has been defined to fit. OO layouts use HO track as an example.
+</p>
+<p>
+<img src="png.d/yellowdot.png"> <img src="png.d/yellowstar.png"> Definitions from this file can be used with this layout but do not fit perfectly. A typical example is On30 where HO scale track can be used because the gauge is the same. But differences in scale may make the track look out of scale. Structures are considered compatible if the scale is within +/-20%. Cars are compatible if the gauge is the same, but the scale can be +/-20%. Exceptions to this can be defined in the scale definitions.
+</p>
+<p>
+<img src="png.d/reddot.png"> <img src="png.d/redstar.png"> This parameter file doesn't contain any usable definitions with current settings. You may want to change the layout options if you want to use elements from this file (for example altering the Layout Scale).
+</p>
+<p>
+<img src="png.d/greydot.png"> <img src="png.d/greystar.png"> This file is loaded but hidden. If it is marked as favorite it will be kept on the list between runs.
+</p>
+<p>
+Parameter files can be marked as <em>favorite</em>. The indicator for favorites is a star. The meaning of the colors isn't changed.
+</p>
+<p>
+Loaded definition files that are marked with a yellow or a green indicator appear on the <strong>Hot Bar</strong> (<a href="cmdHotBar.html#cmdHotBar">Section 2.7</a>).
+</p>
+<p>
+If you <em>unload</em> a file the definitions are removed from the selection lists and the <strong>Hot Bar</strong>. If the unloaded file was marked as a favorite it can be <em>reloaded</em> by selecting the <strong>Reload</strong> button.
+</p>
+<p>
+Files that are still loaded can be <em>reloaded</em> as well. In that case the old definitions are refreshed and extended by the rereading the file. This can be useful if you want to check changes you made by hand-editing a parameter file.
+</p>
+<p>
+Note that loading a file does not change the existing definitions in the layout. To do that after loading, use <a href="cmdRefreshSpecial.html#cmdRefreshSpecial">Section 2.9.10</a>.
+</p>
+<p>
+It is possible to change the state of several files at once. The <strong>Select All</strong> button allows you to select all parameter files for the next operation.
+</p>
+<p>
+In case unloaded files are marked as favorite, their state will be preserved between runs of the program. This makes it possible to keep a list of preferred parameter sets between runs of XTrackCAD but hide temporary unused files from the hotbar. That way the hotbar contents can be kept short containing only the currently needed elements.
+</p>
+<p>
+In order to update the defintion of an already loaded file from disk, you can use the <em>Reload</em> button. This will reload the file contents - with any changes made. It is the equivalent of using <strong>Browse</strong> and selecting the file again.
+</p>
+<p>
+Files can be listed by either their file name or by their contents description. This is controlled by the <strong>Show File Names</strong> check box.
+</p>
+<p>
+The <strong>Library</strong> button opens the <em>Choose Parameter File</em> dialog (<a href="cmdSearchgui.html#cmdSearchgui">Section 2.5.8</a>) this shows the all files included the system library so they can be added.
+</p>
+<p>
+The <strong>Browse</strong> button opens a file window that allows the user to add additional files to directly load other non-system <em>parameter files</em> such as provided by other users or downloaded from the Internet.
+</p>
+<p>
+When first installed, parameter files for all common scales are loaded. You can unload parameter files you don't use to speed up <em>XTrackCAD</em> startup time.
+</p>
+<p>
+The order in this list controls the order of turnouts and structures on the <strong>Hot Bar</strong> (<a href="cmdHotBar.html#cmdHotBar">Section 2.7</a>). You can move a parameter file to the end of the list by <em>Unloading</em> it, and then loading it via the <strong>Browse</strong> button.

+<p>
+<img src="png.d/bprint.png">
+</p>
+<p>
+The <strong>Print</strong> command (<strong>File&gt;Print</strong>) is used to print all or a portion of the layout.
+</p>
+<p>
+<img src="png.d/bsetup.png">
+</p>
+<p>
+The <strong>Print Setup</strong> command (<strong>File&gt;Print Setup</strong>) is used to set up the printer properties.
+</p>
+<p>
+When the <strong>Print</strong> command is selected a grid, which represents each printed page, is drawn on the layout. Pages can be selected or unselected for printing by placing the mouse over a grid section and clicking the left mouse button.
+</p>
+<p>
+<img src="png.d/print.png">
+</p>
+<p>
+The <strong>Print</strong> dialog contains a number of control areas:
+</p>
+<dl><dt>
+The size of each page is controlled by:
+</dt>
+<dd>
+<strong>Scale</strong> - up to 1:1.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<strong>Width, Height</strong> - scaled size of each page. Values for <strong>Width</strong> and <strong>Height</strong> can be manually entered, overriding the maximum values. Values larger than the page size times the <em>Scale</em> cannot be entered.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<strong>Max</strong> - sets Width and Height to the maximum for the print <em>Scale</em>.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<strong>Snap Shot</strong> - adjusts the <em>Scale</em>, <em>Origin</em> and <em>Angle</em> to produce a one-page snap shot of the layout.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<strong>Format</strong> - Portrait or Landscape.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dt>
+Page printing order is controlled by the <strong>Print Order</strong> option.
+</dt>
+<dd>
+Relative to the Print Grid:
+<dl><dd>
+<strong>Normal</strong> order is Columns first, Top to Bottom, Left to Right.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<strong>Reverse</strong> order is Rows first, Left to Right, Bottom to Top.
+</dd>
+</dl>
+
+</dd>
+</dl>
+<p>
+Whether tracks are printed with one or two lines (representing the center line and rails) depends on the <strong>Print Scale</strong>. If this value is smaller than or equal to twice the Two Rail Scale on the Display (<a href="cmdDisplay.html#cmdDisplay">Section 2.10.3</a>) dialog then tracks are drawn with two lines. This corresponds to the way tracks are drawn on the main window, adjusted to account for the greater resolution of most printers. At 1:1 tracks are also drawn with a center line.
+</p>
+<dl><dt>
+Other options:
+</dt>
+<dd>
+<strong>Engineering Data</strong> - show title, user, date and other information in a box at the bottom of the printout.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<strong>Registration Marks</strong> - at 1:1 scale, print location markers every 3" (or 10cm). This option is only enabled at 1:1. This is useful for aligning multiple pages printed at different angles.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<strong>Page Numbers</strong> - to help positioning the individual pages the page number is printed in the center of the page in the format (x/y). x is the page position from left to right, y in from bottom to top, So (1/1) is the page at the bottom left. As an additional aid, the numbers of the next pages are printed on each edge.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<strong>Snap Grid</strong> - if the Snap Grid (<a href="cmdGrid.html#cmdGrid">Section 2.12.2</a>) is visible then it may be drawn on the printout. This option is only enabled if the <em>Snap Grid</em> is visible.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<strong>Rulers</strong> - choose to print rulers at the layout edge, or on all edges of the page, an option is only enabled if the <strong>Angle</strong> is <em>0.000</em>, or None - which means print no rulers.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<strong>Centerline below Scale 1:1</strong> - dotted line down the center of the Track/Roadbed. This line will always be printed at Scale 1:1, but selecting this option will print it at smaller scales. This option is disabled if tracks would be drawn with only one line (instead of two).
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<strong>Roadbed Outline</strong> - lines representing the edge of the Roadbed. The Roadbed will be printed if the <em>Width</em> is greater than the track gauge. Note: this option is most useful at 1:1. This option is disabled if tracks would be drawn with only one line (instead of two).
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<strong>Ignore Page Margins</strong> - use the physical page size. This allows the printouts to abut without trimming.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<strong>Margins</strong> - examine and update the printer margins for the current printer. (<a href="cmdPrintMargin.html#cmdPrintMargin">Section 2.5.11</a>)
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dt>
+The orientation of the print grid is controlled by:
+</dt>
+<dd>
+<strong>X</strong> - X co-ordinate.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<strong>Y</strong> - Y co-ordinate.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<strong>Angle</strong> - of the grid.
+</dd>
+</dl>
+<p>
+These values can be set directly or by dragging on the layout. <code>Shift+Left+Drag</code> moves the grid and <code>Shift+Right+Drag</code> rotates the grid. The <strong>Reset</strong> button resets the values to 0.
+</p>
+<p>
+The <strong>Print</strong> button prints the selected pages and closes the <strong>Print</strong> dialog. It is not enabled until you have selected some pages to print.
+</p>
+<p>
+The <strong>Setup</strong> button invokes the Printer Setup (<a href="printSetup.html#printSetup">Section 2.5.10</a>) dialog.
+</p>
+<p>
+The <strong>Select All</strong> button selects all pages for printing.
+</p>
+<p>
+The <strong>Clear</strong> button unselects all selected pages, so no pages will be printed.
+</p>
+<p>
+<em>Suggested Uses:</em>
+</p>
+<p>
+Use the <strong>Snapshot</strong> button to set the scale and orientation for a one-page printout of the layout. Also set <strong>Engineering Data</strong> to add the Layout Title, Scale and other data for a summary.
+</p>
+<p>
+Use <strong>Layers</strong> (<a href="cmdLayer.html#cmdLayer">Section 2.9.5</a>) to control which tracks are visible (and printed). Put bench-work, scenery or different tracks levels in separate layers and hide the layers you are not working with.
+</p>
+<p>
+To transfer the drawing to the layout without printing at 1:1, make the Snap Grid (<a href="cmdGrid.html#cmdGrid">Section 2.12.2</a>) visible and orient it to match your room or layout table.
+</p>
+<p>
+Check the <strong>Print Snap Grid</strong> toggle and use the printed grid to transfer measurements to your layout space. You may want to change the color (<a href="cmdRgbcolor.html#cmdRgbcolor">Section 2.10.1</a>) of the <strong>Snap Grid</strong> to make it more visible on the printout.
+</p>
+<p>
+When you print multiple pages you can check <strong>Ignore Page Margins</strong> so pages can be placed next to each other. The tracks will line up correctly without trimming or overlapping the pages. Note: depending on your printer there will be an unprintable margin around the edge of the page.
+</p>
+<p>
+If you print at 1:1 for direct transfer to the sub-roadbed, check <strong>Print Roadbed Outline</strong> and set <strong>Width</strong> to show lines for making cuts.
+</p>
+<p>
+If you make printouts in strips at different angles at 1:1 (to follow tracks around a curve), check <em>Print Registration Marks</em> to be able to align the separate strips.

The Description and/or Part Number under each object can be displayed by enabling the <em>Hot Bar Labels</em> radio button on the Display (<a href="cmdDisplay.html#cmdDisplay">Section 2.10.3</a>) dialog.
+</p>
+<p>
+Only those items taken from files which are in the current scale/gauge are displayed in the HotBar. They are shown in order - A Flex-track - then the Contents of Files in the File-&gt;Parameter Files... List in listed order - and then any Custom objects created in this Layout as listed in the Manage-&gt;Custom Defined Parts dialog.
+</p>
+<p>
+The arrow buttons on either side of the <em>Hot bar</em> move the list one object to the right or left. Holding down the Shift key will move the list by greater amounts. About eight <code>Shift+Click</code>s are required to move the list through the entire range of objects. Also, pressing the keys <code>1</code> through <code>9</code> and <code>0</code> will cause the <em>Hot Bar</em> to jump relative spots on the list.
+</p>
+<p>
+A <code>Right-Click</code> over the <em>Hot Bar</em> will display a pop-up menu listing the files with contents on the <em>Hot Bar</em>. Selecting an item from this list causes the <em>Hot Bar</em> to jump to the relative spot on the whole list.
+</p>
+<p>
+Objects on the <em>Hot Bar</em> are placed on the drawing canvas by first selecting an object by <em>Cicking</em> it on the <em>Hot Bar</em>. Then <em>Click</em> and <em>Drag</em> on the Main window, rotating it with <code>Right-Drag</code> to position it, and then pressing the <code>Space</code> key to set it in place.

+<h1><a name="Flex-track"></a>2.7.1 <a name="i0"></a>Flex-track</h1>
+<p>
+A Flex-track unit can be placed for convienience on the left-hand side of the HotBar. This is can be hidden by an option in <a href="cmdPref.html#cmdPref">Section 2.10.7</a>. It can be recognised because it is the only diagonally facing track element and has a label "FLEX". It is used by <code>Left-Click</code> selecting it, and <code>Left-Click</code> clicking on the layout where the first end should be placed, and then <code>Left-Click</code> for the second end. If either end is over an unconnected end and <strong>Shift</strong> was not held, the flex-track will be connected to the track and the end angle and radius will be set from the track. If an end was not over an unconnected end, it can be manipulated by left dragging out the end angle before releasing. If the second end is not on a track end, differing end angles will produce a smooth curve, if both ends are unconnected, simply <code>Left-Click</code> without dragging produces a straight track. Once both ends have been defined, the track can then be manipulated like a <a href="chgCornu.html#chgCornu">section 2.2.8.8</a> Cornu Curved Track, by selecting and moving ends, adding and removing "pins" and altering the end anchor angle and radius if the flex-track is not connected at that end. If the disconnected end is dragged and the button released while over an open end of another track, it will be connected to it in the manner of a Join with a Cornu easement.
+</p>
+<p>
+A Flex-track will form a Straight Track if the ends have zero radius and are in a line with opposed end angles. If the ends are not aligned but the end angles are opposed it will be a simple S-curve. It will be a smooth monotonic curve if the ends are not in a line and the end angle lines and chord form a triangle. Otherwise it will be a complex S-curve. .

+<em>Turnouts</em> have an <em>Active EndPoint</em> (<a href="generalTerms.html#generalTerms">Section B.2</a>) which is the handle used to position the <em>Turnout</em>. You can change the <em>Active EndPoint</em> by a <code>Shift+Left-Click</code> which causes the next endpoint to become Active.
+</p>
+<p>
+If you <code>Left+Drag</code> a turnout onto a track, the Active EndPoint (<a href="generalTerms.html#generalTerms">Section B.2</a>) is aligned with the selected track. On flex-track, you can flip the turnout by moving the cursor from one side of the track centerline to the other. On another turnout, the new turnout will be placed at the endpoint closest to the cursor.
+</p>
+<p>
+<em>XTrackCAD</em> will automatically connect the turnout's endpoints to any other tracks they are aligned with. The number of endpoints that will be connected is displayed on the Status Bar, as well as the Maximum displacement between these endpoints and the tracks they will be connected to. <em>XTrackCAD</em> will adjust the position of the Turnout to give you the best fit for locating the turnout. You can override this adjustment by holding down the <em>Shift</em> key while <em>Dragging</em>.
+</p>
+<p>
+<code>Right+Drag</code> or <code>Ctrl+Left+Drag</code> (<a href="windowTerms.html#windowTerms">Section B.1</a>) can be used to rotate the turnout on the layout. <code>Shift+Right-Click</code> (<a href="cmdAcclKeys.html#cmdAcclKeys">Section 3.4</a>) displays a pop-up menu allowing you to rotate the turnout by various angles.
+</p>
+<p>
+When you press the <code>Space</code> key, the turnout is positioned on the layout. Any tracks that are aligned with any of the turnout's endpoints will be connected to the turnout automatically. If you are using the Turnout (<a href="cmdNewFixedTrack.html#cmdNewFixedTrack">Section 2.1.8</a>) command then you can also click the <em>OK</em> button on the dialog.
+</p>
+<p>
+If you choose another turnout or change commands after beginning to place a turnout on the layout, the turnout will be created as if it is attached to another track. Otherwise it will be removed.
+</p>
+<p>
+If the Drawing Scale is smaller or equal to the Label Scale (<a href="cmdDisplay.html#cmdDisplay">Section 2.10.3</a>) then Turnouts will be labeled with their description when drawn. The individual labels can be can be turned off by the Move Description(<a href="cmdMoveLabel.html#cmdMoveLabel">Section 2.2.10</a>) command, or all Turnout labels can be disabled by using the Display (<a href="cmdDisplay.html#cmdDisplay">Section 2.10.3</a>) dialog. As well, the length of any connected Flex-track will be indicated at each endpoint.

+<h1><a name="cmdCarinv"></a>2.9.1 <a name="i0"></a>Car Inventory</h1>
+<p>
+This dialog is used to manage your list of cars and locomotives.
+</p>
+<p>
+<img src="png.d/carinv.png">
+</p>
+<p>
+The main part of this dialog contains a detailed list of each car and locomotive in your inventory. The list can be sorted on different columns by selecting column names in the <strong>Sort Drop Down Lists</strong> along the top of the dialog. The width of the columns can be adjusted by <em>Left+Drag</em> on the lines between the column titles.
+</p>
+<p>
+Cars are placed on the layout by using the <strong>Train Simulation</strong> (<a href="cmdTrain.html#cmdTrain">Section 2.9.8</a>) command.
+</p>
+<p>
+The <strong>Find</strong> button will center the <strong>Main Window</strong> (<a href="mainW.html#mainW">Section 3.1</a>) on the selected car. This button is only enabled for cars which are on the Layout (indicated by co-ordinates in the Location column). If the car on a track that is hidden and <strong>Trains on Hidden Track</strong> (<a href="cmdDisplay.html#cmdDisplay">Section 2.10.3</a>) is set to <strong>Hide</strong>, then the car (and any attached cars) will be made visible.
+</p>
+<p>
+The <strong>Edit</strong> button invokes the <strong>Car</strong> dialog (<a href="cmdCarpart.html#cmdCarpart">Section 2.9.1.1</a>) to modify the selected car. This button is disabled if more than one (or no) car is selected or if the selected car is on the Layout.
+</p>
+<p>
+The <strong>Add</strong> button is to add a new Car. Refer to <a href="faqsPrototype.html#faqsPrototype">Section A.3</a> if an error occurs when attempting to add inventory to this list.
+</p>
+<p>
+The <strong>Delete|Shelve</strong> button serves two functions: If all selected cars are on the layout then this button shows <strong>Shelve</strong> and it moves them from the layout and returns them to the <strong>Shelf</strong>. If all selected cars are on the <strong>Shelf</strong> then this button shows <strong>Delete</strong> and they will be deleted from the Inventory. Otherwise, the button is blank and disabled.
+</p>
+<p>
+The <strong>Import</strong> and <strong>Export</strong> buttons read and write a <em>Comma-Separated-Value (CSV)</em> file. This file format can be read and written by many applications. It can be used to transfer car inventory data between different applications. This file contains the following columns (the first four are required when Importing):

+</p>
+<p>
+The dialog can be displayed in three different ways and is used to create or edit <strong>Car Items</strong>, <strong>Car Part</strong> definitions or <strong>Prototype</strong> definitions.
+</p>
+<p>
+The <strong>Add</strong> button creates a new definition. The dialog remains open so you can enter multiple definitions. You can <strong>Close</strong> the dialog when you are finished. If you are editing an existing definition then the <strong>Add</strong> button will be replaced by the <strong>Update</strong> button which updates the selected definition and closes the dialog.
+</p>
+<p>
+The <strong>New</strong> button on the <strong>Car Item</strong> dialog invokes the <strong>Car Part</strong> or <strong>Car Prototype</strong> dialog which you can use to create new part or prototype definitions for your cars. The <strong>New</strong> button on the <strong>Car Part</strong> dialog invokes the <strong>Car Prototype</strong> dialog.
+</p>
+<p>
+<strong>Car Item Dialog</strong>

The <strong>Manufacturer</strong> Drop Down List is editable so you can enter a new manufacturer, and you must enter a <strong>Part Number</strong>. If you are adding a new car part, the <strong>Part Number</strong> field will be incremented (if it is a numeric value) so you can enter a number of car parts.

You can choose a <strong>Road name</strong> from the list of known road names or enter a new value. If known, the <em>reporting mark</em> (road name abbreviation) is filled in. These values control what label content is shown for Cars.

+<strong>Car Dimensions</strong> which contain the major dimensions of the car and how the coupler is mounted on the car.

+The <em>Center Offset</em> moves the center of the two trucks from the center of the Car. This is a common feature of steam locomotives and means the envelope of the engine requires greater seperation between tracks on small radius curves. The minimum clearance needed can be seen by placing the car with the greatest distance from the center of the trucks to the corner on the inner radius and the car with the greatest distance between the trucks on the outer radius. See NMRA TN-7 Curved Track Centerline and Obstacle Clearance Calculation Methodology.

+<h1><a name="carprototype"></a>2.9.1.3 <a name="i0"></a>Car Prototype Dialog</h1>
+<p>
+This dialog is used to create or edit prototype definitions.
+</p>
+<p>
+<img src="png.d/carproto.png">
+</p>
+<p>
+The first section contains the name of the <strong>Prototype</strong> and its <strong>Type</strong>.
+</p>
+<p>
+If this dialog was invoked from the <strong>Car Item</strong> or <strong>Car Part</strong> dialog then the prototype diagram will be copied from the selected part. Otherwise, the prototype is drawn as the default image which is a simple blue rectangle or, if it is a locomotive, with one end angled.
+</p>
+<p>
+The <strong>Import</strong> button creates a prototype definition from the selected (<a href="cmdSelect.html#cmdSelect">Section 2.2.16</a>) lines and shapes. To use this, first create a set of shapes (<strong>Filled Rectangles, Polygons, Circles, Lines</strong> etc) using the Draw (<a href="cmdDraw.html#cmdDraw">Section 2.3</a>) commands on the main canvas. <strong>Select</strong> the shapes and use the <strong>Import</strong> button.
+</p>
+<p>
+The <strong>Reset</strong> button will reset the figure to the default image.
+</p>
+<p>
+If this dialog is invoked by the <strong>New</strong> button on the <strong>Car</strong> or <strong>Car Part</strong> dialog then the initial image will be copied from the prototype displayed on those dialogs. You can use this to make variations of existing prototypes.
+</p>
+<p>
+The <strong>Color</strong> control on the <strong>Car Part</strong> dialog will replace any color of the <strong>Imported</strong> shapes which is not Black or a shade of gray with the selected hue.
+</p>
+<p>
+The <strong>Flip</strong> button flips the diagram horizontally. For locomotives, the forward direction is to the right.
+</p>
+<p>
+Unlike the other dialogs, dimensions in this dialog are in prototype units. When entering values, the <code>s</code> key will convert a scale measurement to a prototype measurement.

+<h1><a name="cmdContmgm"></a>2.9.3 <a name="i0"></a>Layout Control Elements Dialog</h1>
+<p>
+This dialog is used to manage layout control elements (blocks, switchmotors, and signals).
+</p>
+<p>
+Control Elements are elements related to layout control: blocks (occupancy detection), switchmotors (actuators to "throw" turnouts), signals, controls (other actuator or output devices), and sensors (other sensor or input devices). These elements don't relate to directly "physical" items on the layout, but instead refer to the elements used by the layout control software. These elements contain "scripts", which are really just textual items that provide information for the layout control software and provide a bridge between physical layout elements (like tracks or turnouts) and the layout control software. These textual items could be actual software code or could be LCC Events (for I/O device elements on a LCC network) or DCC addresses for stationary decoders, etc. XTrackCAD does not impose any sort of syntax or format -- that is left up to other software that might load and parse the XTrkCAD layout file. All that XTrackCAD does is provide a unified place for this information to be stored and to provide a mapping (association) between this control information and the layout itself.
+</p>
+<p>
+<img src="png.d/lcemanager.png">
+</p>
+<p>
+The main part of this dialog contains a list of the currently defined layout control elements (blocks, switchmotors, signals, controls, and sensors), along with the tracks they relate to. These elements are added to the layout either from their Hotbar menus or from the Add menu.
+</p>
+<p>
+The <strong>Edit</strong> button allows for editing a control element. And the <strong>Delete</strong> button deletes the selected element(s).

+<h1><a name="cmdGroup"></a>2.9.4 <a name="i0"></a>Group Dialog</h1>
+<p>
+The <strong>Group</strong> command combines the selected (<a href="cmdSelect.html#cmdSelect">Section 2.2.16</a>) Lines and Shapes (<a href="cmdDraw.html#cmdDraw">Section 2.3</a>) to create structures (<a href="cmdHotBar.html#cmdHotBar">Section 2.7</a>). You can give the structure (<a href="cmdHotBar.html#cmdHotBar">Section 2.7</a>) a title consisting of Manufacturer, Description and Part Number on the <strong>Group</strong> dialog.
+</p>
+<p>
+<img src="png.d/cgroup.png">
+</p>
+<p>
+The title will be pre-populated with the title of the last <strong>Structure</strong> you <strong>ungrouped</strong> (<a href="manageM.html#manageM">Section 2.9</a>).
+</p>
+<p>
+You can include <strong>Turnouts</strong>, <strong>Sectional</strong>, <strong>Straight</strong> or <strong>Curved</strong> tracks in the selected objects which allows you to add cosmetic details to a <strong>Turnout</strong> definitions, or create a new <strong>Turnout</strong> definition. This can also be used to if there are fixed-track locations on a structure, like on an engine shed.
+</p>
+<p>
+<strong>Group</strong> is intended to operate on simple groups of track segments. If you intend to group a large number of track segments, you should consider using <strong>Import Module</strong> (see <a href="cmdLayer.html#cmdLayer">Section 2.9.5</a>),
+</p>
+<p>
+To modify a <strong>Structure</strong> or <strong>Turnout</strong> definition, first place the object on the layout, select and then <strong>Ungroup</strong> the object. Now the parts of the object can be edited using the <strong>Modify</strong> (<a href="cmdModify.html#cmdModify">Section 2.2.8</a>), <strong>Draw</strong> (<a href="cmdDraw.html#cmdDraw">Section 2.3</a>) or other commands. Once completed, select the object parts and use the <strong>Group</strong> command to update the definition (or create a new one by changing the title).
+</p>
+<p>
+The <strong>Group</strong> dialog shows the Manufacturer, Description and part number (Title) of the new definition. Initial values are based on selected turnouts and structures or on the last <strong>Ungroup</strong>ed object (<a href="cmdUngroup.html#cmdUngroup">Section 2.9.11</a>). The <strong>Turntable/TransferTable/DblSlipSwitch</strong>? toggle button controls whether non-conflicting <strong>Paths</strong> should be combined or keep separate, see <strong>Paths</strong> below. The <strong>Replace with new group</strong>? toggle button is used if you want to replace the selected objects with the new definition. All fields listed in this dialog window must contain data.
+</p>
+<p>
+The definition data will be added to the <code>xtrkcad.cus</code> (<a href="directories.html#directories">Section 1.9</a>) file for later use. Please consider contributing this information for others to use.
+</p>
+<p>
+If you modify a definition from a <em>XTrackCAD</em> Library parameter file, the new definition will replace the existing definition on the <strong>Hot Bar</strong> (<a href="cmdHotBar.html#cmdHotBar">Section 2.7</a>), otherwise it will be added to the end of the <strong>Hot Bar</strong>. You can use the <strong>Custom Management</strong> (<a href="cmdCustmgm.html#cmdCustmgm">Section 2.9.2</a>) dialog to change the title or delete custom definitions.
+</p>
+<p>
+<strong>Note:</strong> The selected tracks are decomposed into segments, which are simple tracks and drawing object (lines, curves, polygons ... ). Any track segments must appear in the first 127 segments. This implies a limit of 127 track segments.
+</p>
+<dl><dd>
+You can re-order the segment list by
+<ul><li>
+Ungroup the selected tracks
+</li>
+<li>
+Unselect all, and select the tracks you want to group
+</li>
+<li>
+<strong>Move selected objects to bottom</strong>
+</li>
+<li>
+Add the non-tracks object to the selected track segments
+</li>
+<li>
+Retry the <strong>Group</strong> command
+</li>
+</ul>
+
+</dd>
+</dl>
+<p>
+<strong>Paths</strong> define which segments are followed by a train in Train mode. Normally, if two paths follow paths of separate segments, then the paths are combined. For example a simple turnout would have two paths, but since the paths share some common segments, the paths are not combined. A Crossing has two paths but since they don't have any segments in common, the two paths are combined into one. A Turntable can have many distinct paths but only one would be valid at any time. In this case we don't want to combine paths and the toggle would be checked.

+<h1><a name="cmdLayer"></a>2.9.5 <a name="i0"></a>Layers Dialog</h1>
+<p>
+Each object is contained in a layer - which is a custom group of objects that do not have a particular visual order, but can be treated as a set for certain commands. Objects which are created independently of other objects (such as straight tracks (<a href="cmdStraight.html#cmdStraight">Section 2.1.6</a>) or text (<a href="cmdText.html#cmdText">Section 2.3.9</a>)) are created in the current layer. Objects which are associated with other objects (such as tracks created by the <strong>Modify</strong> (<a href="cmdModify.html#cmdModify">Section 2.2.8</a>) or <strong>Join</strong> (<a href="cmdJoin.html#cmdJoin">Section 2.2.7</a>) commands) are created in the same layer as the associated object(s).
+</p>
+<p>
+The <strong>Layers</strong> dialog allows you to change various attributes of each of the 99 possible <strong>layers</strong>.
+</p>
+<p>
+Attributes associated with a layout are stored within the associated layout file and apply only to the layout that's open at the time of a change. It is possible to apply attributes from one layout file to another using the <strong>Load</strong> and <strong>Save</strong> buttons.
+</p>
+<p>
+<img src="png.d/dlayers.png">
+</p>
+<p>
+The drop down list at the top of the dialog selects the <strong>Layer</strong> you are interested in. Frozen layers are preceeded by a <code>*</code>, Module layers are proceeded by a <code>m</code>, non-empty layers are preceded by a <code>+</code> and empty layers by a <code>-</code>.
+</p>
+<p>
+The <strong>Name</strong> edit box contains the name of the <strong>Layer</strong>. This name is listed in the <strong>Current Layer</strong> drop down list on the <strong>Tool-bar</strong> (<a href="mainW.html#mainW">Section 3.1</a>). Also the <strong>Name</strong> is displayed as the balloon help for the corresponding <strong>Layer Button</strong>.
+</p>
+<p>
+The <strong>Color</strong> button specifies the color of tracks if either of the two <strong>Color Layers</strong> (<a href="cmdDisplay.html#cmdDisplay">Section 2.10.3</a>) radio buttons on the <strong>Display</strong> dialog is checked and the <strong>Use Color</strong> button for this layer is checked.
+</p>
+<p>
+The <strong>Visible</strong> check-box controls whether the <strong>Layer</strong> is drawn on the Main (<a href="mainW.html#mainW">Section 3.1</a>) window.
+</p>
+<p>
+The <strong>Frozen</strong> check-box indicates that tracks in that <strong>Layer</strong> can not be modified or deleted.
+</p>
+<p>
+The <strong>On Map</strong> check-box controls whether the <strong>Layer</strong> is drawn on the Map (<a href="cmdMap.html#cmdMap">Section 3.2.2</a>) window.
+</p>
+<p>
+The <strong>Module</strong> check-box controls whether the <strong>Layer</strong> is selected/deselected and so moved or rotated as a group - this can be used to denote a track module in a modular layout - allowing the modules to be positioned as units. Objects in a Module Layer can not be individually modified. One way of getting a modules in is to build a library with <strong>Export</strong> and then <strong>Import As Module</strong> - this creates one layer per module, names it and sets the <strong>Module</strong> check-box.
+</p>
+<p>
+The <strong>No Button</strong> check-box selects if the <strong>Layer</strong> has a button to hide/show it. You may choose not to have a button if the layer is empty or if it is a sub-layer controlled by another layer.
+</p>
+<p>
+The <strong>Linked Layers</strong> text box can contain a semi-colon-delimited set of layer numbers that will be shown and hidden along with this layer when its show/hidden state is changed. A blank means no layers are linked. The layers can have buttons or not.
+</p>
+<p>
+You cannot uncheck <strong>Visible</strong> or check <strong>Frozen</strong> for the <strong>Current Layer</strong>.
+</p>
+<p>
+The <strong>Load Settings</strong> specifies a settings (.xset) filename in the XTrackCAD working directory that is loaded when this layer is made current. Only the values contained in the file will be set. If this name is blank the default values (all those in use when any layer that has no Load Settings file value was last used) will be reloaded (or retained). The dropbox contains all the names of files in that directory.
+</p>
+<p>
+The <strong>Count</strong> field displays the number of objects in the selected Layer.
+</p>
+<p>
+The <strong>Save</strong> button stores layer attributes in the <code>xtrkcad.ini</code> file so they may be loaded into an existing or new file. Once saved and unless reset to <em>XTrackCAD</em> <strong>Default</strong>, modified layer information is applied to each new file.
+</p>
+<p>
+The <strong>Load</strong> button reads layer attributes from the <code>xtrkcad.ini</code> file then applies it to each layer of the current layout file.
+</p>
+<p>
+The <strong>Defaults</strong> button restores layer attributes to default <em>XTrackCAD</em> settings.
+</p>
+<p>
+The bottom of the dialog contains the <strong>Number of Layer Buttons</strong> integer edit box. This controls the number of <strong>Layer Buttons</strong> displayed on the <strong>Tool-bar</strong> (<a href="mainW.html#mainW">Section 3.1</a>). These buttons make it easy to switch between layers. The maximum number of <strong>Layer Buttons</strong> that can be displayed is 99. Layers with "no-button" set do not count towards the Number of Layer Buttons.
+</p>
+<p>
+<img src="png.d/blayer.png">
+</p>
+<p>
+The <strong>Layer Buttons</strong> on the Tool-bar (<a href="mainW.html#mainW">Section 3.1</a>) control which layer is the <strong>current Layer</strong> and which <strong>Layers</strong> are displayed on the Main Canvas. These buttons are a short cut for the <strong>Visible</strong> check-box on the <strong>Layers</strong> dialog for the corresponding layer.
+</p>
+<p>
+The current layer is selected by picking a value from the drop down layer list. If the Layer you've selected was not visible, it will be shown.
+</p>
+<p>
+You can hide (or show if not visible) the different layers by pushing one of the <strong>Layer Buttons</strong> on the Tool-bar (if you have configured the tool-bar (<a href="toolbarM.html#toolbarM">Section 2.12.3</a>) to show the Layer buttons). If a layer is not visible then the corresponding layer button will be raised. The active or current layer cannot be hidden.
+</p>
+<p>
+The color of each layer button shows the color that will be used to draw tracks or draw objects in that layer, if you have selected the <strong>Color Layers</strong> (<a href="cmdDisplay.html#cmdDisplay">Section 2.10.3</a>) on the <strong>Display</strong> dialog. The <strong>Use Color</strong> button allows this layer to opt in or out - which can be usefu if you want to color other layers but a layer contains pre-colored objects (like Structures or Scenery).
+</p>
+<p>
+Any selected objects are unselected when the Layer is set to not visible. If a layer is not visible, you cannot select objects in the Layer. It is as if the objects do not exist until you show the layer again.
+</p>
+<p>
+The <strong>Move To Current Layer</strong> command on Edit menu (<a href="editM.html#editM">Section 2.4</a>) will move all selected (<a href="cmdSelect.html#cmdSelect">Section 2.2.16</a>) tracks to the current Layer.
+</p>
+<p>
+Objects are drawn on the map window, if the Layer they are on has <strong>On Map</strong> checked.

+<h1><a name="cmdTurnoutNew"></a>2.9.9 <a name="i0"></a>Turnout Designer</h1>
+<p>
+The <strong>Turnout Designer</strong> allows you to define new turnouts and sectional track pieces.
+</p>
+<p>
+<img src="png.d/mmanageturnoutdesign.png">
+</p>
+<p>
+The Turnout Designer sub-menu is pictured above. As demonstrated by the sub-menu a number of different dialogs are available for creation of custom turnout and sectional track components. New turnouts and sectional track is added to Custom Management (<a href="cmdCustmgm.html#cmdCustmgm">Section 2.9.2</a>) and Turnout Manager (<a href="cmdNewFixedTrack.html#cmdNewFixedTrack">Section 2.1.8</a>) using the <strong>Turnout Designer</strong>.
+</p>
+<p>
+The follow dialog is for a regular turnout.
+</p>
+<p>
+<img src="png.d/turndes.png">
+</p>
+<p>
+Each dialog shows a diagram of the turnout and has fields to enter dimensions. The dimensions should be as accurate as possible. The various types of dimensions are:
+</p>
+<dl><dd>
+<strong>Length</strong> - measured from the base of the turnout to the centerline at the end of the turnout. Length is measured parallel to the centerline of the straight leg of the turnout. For track that ends on a curve (such as the curved leg of a regular turnout) measure the distance from the base to each rail and average the values.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<strong>Offset</strong> - measured from the centerline of the straight leg of the turnout to the centerline of the track at the end of the turnout.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<strong>Angle</strong> - angle at the end of turnout to the centerline of the straight leg of the turnout. This angle may not be the same as the <em>Frog</em> angle of the turnout if the rails curve past the <em>Frog</em>. The <strong>Frog Number|Degrees</strong> Radio button group controls whether the value is expressed in Frog Number or Degrees.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<strong>Manufacturer</strong> - name of the Manufacturer
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<strong>Description</strong> - description of the turnout including size and rail code number, e.g., 'Left Hand #4'. This information is shown when a place the mouse pointer over the respective symbol on th <strong>Tool-bar</strong>. Therefor it should be made sure that the data entered here are helpful in finding the correct turnout.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<strong>#</strong> - part number, e.g., '999-123'.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<strong>Roadbed Width</strong> - if greater than the track gauge then lines are drawn along the edges of the turnout to represent the attached roadbed available on some types of sectional track and turnouts.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<strong>Line Width</strong> - the width of the roadbed lines, measured in pixels when the layout drawing scale (<a href="viewM.html#viewM">Section 2.12</a>) is 1:1.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+<strong>Color</strong> - color of the roadbed lines.
+</dd>
+</dl>
+<p>
+
+</p>
+<p>
+The rail height (<em>Code</em>) can be added to the <strong>Manufacturer</strong>, e.g., Peco-55, or the <strong>Description</strong>, e.g., Medium Right, Code 55.
+</p>
+<p>
+The scale is the current scale from the <strong>Scale Drop Down List</strong> on the <strong>Layout</strong> dialog (<a href="cmdLayout.html#cmdLayout">Section 2.10.6</a>).
+</p>
+<p>
+<strong>Manufacturer</strong>, <strong>Description</strong> and <strong>Part Number (#)</strong> comprise the title of the turnout. These values are used in the <strong>Turnout Selection dialog</strong> (<a href="cmdNewFixedTrack.html#cmdNewFixedTrack">Section 2.1.8</a>) and the <strong>Parts List</strong> (<a href="cmdEnum.html#cmdEnum">Section 2.9.6</a>). For regular and curved turnouts there are separate <strong>Descriptions</strong> and <strong>Part Numbers</strong> for the right and left hand turnouts.
+</p>
+<p>
+The <strong>Print</strong> button prints a full size diagram of the turnout. You can use this to check your dimensions and make any required changes. You should expect to make several printouts as you refine your dimensions.
+</p>
+<p>
+The <strong>OK</strong> button completes the design. The new turnout is added to the list in the <strong>Turnout Selection</strong> dialog. The turnout data is saved in the <code>xtrkcad.cus</code> (<a href="directories.html#directories">Section 1.9</a>) file for the next time you use <em>XTrackCAD</em>. Please consider contributing this information for others to use via the on-line addresses. You can change the Parameters or Title of existing designs by using the <strong>Custom Management</strong> (<a href="cmdCustmgm.html#cmdCustmgm">Section 2.9.2</a>) dialog.
+</p>
+<p>
+The <strong>Cancel</strong> button removes the <strong>Turnout Designer</strong> dialog.
+</p>
+<p>
+<em>Creating Turnout Designs</em>
+</p>
+<ul><li>
+It is best to start by marking the endpoints of the turnout on a piece of paper. Extend the curved leg of the turnout (try attaching a straight sectional track) and measure the angle. Frog numbers are easiest to calculate.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+Enter your data and press <strong>Print</strong>, if you have an accurate printer. Check the dimensions of the turnout against the printout and make adjustments as necessary. Concentrate on the lengths and offsets first, then adjust the angles.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+The resulting turnout is an approximation. In particular the curves will not be correct, but this is not important for placing turnouts.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+The new <a name="i1"></a>Cornu Turnouts allow you to build turnouts that have curved ends. The dialogs include radius information that can be set to zero for a straight end. The turnouts will be composed of simple curves and tracks and when extended the end radius will be used.
+</li>
+<li>
+The Group (<a href="cmdGroup.html#cmdGroup">Section 2.9.4</a>) command can be used to add cosmetic details to <strong>Turnout</strong> definitions.

+<h1><a name="cmdRefreshSpecial"></a>2.9.10 <a name="i0"></a>Update Turnouts and Structures</h1>
+<p>
+This command updates (or refreshes) selected turnouts, sectional tracks and structures on your layout with the current definitions from the loaded parameter files (<a href="cmdPrmfile.html#cmdPrmfile">Section 2.5.7</a>). Each selected object that is found in a parameter file is updated with the current definition.
+</p>
+<p>
+If an object can be found and if a new track definition fits in the same footprint, (i.e., has the same number of endpoints and all the endpoints have the same position and angle) then a dialog is displayed which contains suitable definitions that you can choose from. You can <strong>Skip</strong> the current object or <strong>Cancel</strong> to skip all the remaining objects.
+</p>
+<p>
+Otherwise the update fails and must be done manually using <strong>Delete</strong> and <strong>Add</strong>.
+</p>
+<p>
+If an object has been updated then it is unselected, otherwise it will remain selected at the end of this command.

+<p>
+<strong>Ungroup</strong> allows existing definitions to be modified and the resulting objects recombined with the <strong>Group</strong> (<a href="cmdGroup.html#cmdGroup">Section 2.9.4</a>) command to update the definition. Turnouts are composed of individual straight and curved segments. Segments that form the points (<a href="generalTerms.html#generalTerms">Section B.2</a>) of the turnout remain combined as an <em>Ungrouped Turnout</em>, and the other segments are replaced by straight and curved tracks.
+</p>
+<p>
+One-ended Turnouts (AKA Bumpers) are converted to Staight tracks by <strong>Ungroup</strong>. These can be converted back to a Bumper by manually editting the <strong>Grouped</strong> definition and removing the unwanted End-Point by deleting the correspnding <strong>E</strong> line.

+<h1><a name="cmdEasement"></a>2.10.4 <a name="i0"></a>Easements</h1>
+<p>
+Easements are special sections of gradually curving track used to connect straight and curved tracks (or two curved tracks). Easements reduce the effects of sudden changes in track curves which can cause jerky motion and derailments.
+</p>
+<p>
+Easements can be created every time you <strong>Join</strong> (<a href="cmdJoin.html#cmdJoin">Section 2.2.7</a>) tracks, <strong>Extend</strong> (<a href="extendTrack.html#extendTrack">Section 2.2.8.6</a>) a track or create a <strong>Tangent</strong> (<a href="createTangent.html#createTangent">Section 2.2.8.4</a>) track.
+</p>
+<p>
+When using easements, an error message will be generated if tracks have a radius that is too small or are too short for the transition curve.
+</p>
+<p>
+The <strong>Easement</strong> dialog is invoked from the Options (<a href="optionM.html#optionM">Section 2.10</a>) menu.

+<h1><a name="EasementsCornu"></a>2.10.4.1 <a name="i0"></a>Cornu Easements</h1>
+<p>
+The Cornu Easements work in a different way to the other easements. They use all the space available to minimize sharpness, so you can control the sharpness for each curve you draw by the distance apart, radius and angle of the two end points.
+</p>
+<p>
+The Cornu is a mathematical curve that has the property that the curvature (inverse of the radius) varies linearly along its length. Using an open-source Cornu library written by Dr Raph Levin, we can calculate an Cornu easment to suit the end conditions of radius, curve center, angle and position. A Cornu easement can be constructed between two tracks by using the values of these parameters.
+</p>
+<p>
+To draw an cornu easement see <a href="joinCornu.html#joinCornu">section 2.2.7.4</a>, to Modify it afterwards see <a href="chgCornu.html#chgCornu">section 2.2.8.8</a>.

+<p>
+The values <strong>R</strong>, <strong>X</strong> and <strong>L</strong> are read-only. They are set using the radio buttons or the <strong>Value</strong> field which can be set to 0 (No Easment) or between 0.21 (sharpest Easement) 100 (broadest Easment).
+</p>
+<p>
+These values indicate the worst case of joining a straight track with a curve of radius <strong>R</strong>. The two tracks are separated by the offset <strong>X</strong> while the easement curve extends for <strong>L/2</strong> inches or centimeters to each side of the endpoints.
+</p>
+<p>
+The formula used to draw non-Cornu easements is:
+</p>
+<pre><code>         x = l * l * l / (6 * <b>R</b> * <b>L</b>)
+         r = <b>L</b> * <b>R</b>/l
+</code></pre>
+<p>
+where
+</p>
+<ul><li>
+<strong>l</strong> is the distance along the tangent to the easement.
+</li>
+<li>
+<strong>R</strong> is the final radius of the easement.
+</li>
+<li>
+<strong>L</strong> is the total length of the easement along the tangent.
+</li>
+<li>
+<strong>x</strong> is the offset from the tangent at <strong>l</strong>.
+</li>
+<li>
+<strong>r</strong> is the radius of easement curve at <strong>l</strong>.
+</li>
+</ul>
+<p>
+The Easement Button (<img src="png.d/beasement.png">) on the Main Window (<a href="mainW.html#mainW">Section 3.1</a>) changes its label to indicate the current easement value.
+</p>
+<p>
+The following diagrams illustrates the <strong>R</strong>, <strong>X</strong> and <strong>L</strong> values and the resulting easement curve.
+</p>
+<p>
+<img src="png.d/easeex1.png">
+</p>
+<p>
+<img src="png.d/easeex2.png">
+</p>
+<p>
+If curves with a radius larger than <strong>R</strong> or two curves (that bend in the same direction) are being connecting then the easement curve will be shorter and the offset smaller. If the computed offset is small then no easement is generated.
+</p>
+<p>
+A curved track that bends in one direction and then bends in the opposite direction is an <em>S-curve</em>. This will generate the worst case easement which is two easement curves placed end to end.

+<h1><a name="cmdMagneticSnap"></a>2.12.1 Magnetic Snap</h1>
+<p>
+The <strong>MagneticSnap</strong> feature eases constructing and assembling Tracks and Draw objects by "snapping" the end of new objects to existing objects. For existing track objects the point snapped to is always an open end point. The snap operates when "close" to the object (a few pixels distant) and an anchor point (a blue circle) is displayed when this will occur if the mouse is clicked.
+</p>
+<p>
+ When Adding Draw line objects, the snap point is the nearest point on the existing object. A snap to the end of a line object can be selected by positioning the cursor close to the end of the line but off it, in the direction of the line. This will ensure the closest point is the end.
+</p>
+<p>
+ The <strong>MagneticSnap</strong> feature is enabled and disabled using either the magnet icon which is part of the <strong>SnapGrid</strong> Toolbar button set, or using the View (<a href="viewM.html#viewM">Section 2.12</a>) menu.
+</p>
+<p>
+For each part of an Add or Move or Rotate operation, the current state of <strong>MagneticSnap</strong> can be temporarily inverted using the <strong>Alt</strong> key. This enables snapping to be inhibited for a single part of an operation (or conversely enabled for just one part).

+<p>
+The <strong>Grid</strong> dialog, displayed by <strong>Change Grid</strong> on the View (<a href="viewM.html#viewM">Section 2.12</a>) menu, specifies the origin, angle and other parameters of the Snap Grid. The Snap Grid can sbe used to snap the position of the cursor during the <strong>Curve</strong> (<a href="cmdCurve.html#cmdCurve">Section 2.1.2</a>), <strong>Circle</strong> (<a href="cmdCircle.html#cmdCircle">Section 2.1.1</a>), <strong>Cornu</strong> (<a href="cmdCornu.html#cmdCornu">Section 2.1.2.6</a>), <strong>Modify</strong> (<a href="cmdModify.html#cmdModify">Section 2.2.8</a>), <strong>Straight</strong> (<a href="cmdStraight.html#cmdStraight">Section 2.1.6</a>), <strong>Draw</strong> (<a href="cmdDraw.html#cmdDraw">Section 2.3</a>) and <strong>Turntable</strong> (<a href="cmdTurntable.html#cmdTurntable">Section 2.1.9</a>) commands.
+</p>
+<p>
+<img src="png.d/grid.png">
+</p>
+<p>
+The <strong>Grid</strong> dialog contains controls affecting the horizontal and vertical snap grid lines. Each dimension can be independently controlled.
+</p>
+<dl><dd>
+The <strong>Spacing</strong> value specifies the distance between major grid lines, which are drawn as solid lines on the layout. The value of the distance is entered in either inches or centimeters depending on the value of the <strong>Units</strong> setting in Options-&gt;Preferencecs (<a href="cmdPref.html#cmdPref">Section 2.10.7</a>) menu.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+The <strong>Divisions</strong> value adds the minor Grid lines between the major Grid lines, which are drawn as a series of dots on the layout. Specifying a value of 0 or 1 as the division value removes the minor grid lines.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+The Grid can be enabled or disabled in each dimension via the <strong>Enable</strong> check box. The action of snapping is secondary to <strong>Magnetic Snap</strong> if enabled, and is suppressed if <strong>Alt</strong> is held.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+The <strong>X</strong> and <strong>Y</strong> coordinates relate to the anchor point of the X and Y Axis. Default values for <strong>X</strong> and <strong>Y</strong> are zero (0). Entering a value of one for <strong>X</strong> causes the Main grid line on the Drawing Canvas to shift left one unit. Entering a value of two causes the Main grid line to shift by two units and so on. The <strong>Y</strong> axis is affected in the similar manner except the grid moves down rather than left.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+Negative values can be used for X and Y values. Using such cause the Main Grid to shift right for the X Axis and up for the Y Axis.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+The A coordinate relates to the Angle of grid rotation. The default value for this coordinate is zero. Entering a value greater than 0 and less than 90 will cause the Main Grid to rotate clockwise by the number of degrees entered. Entering a negative value causes the grid to rotate counter-clockwise.
+</dd>
+</dl>
+<p>
+The origin and angle of the Grid can be adjusted directly or by dragging on the layout. <em>Left+Drag</em> moves the origin of the Grid, and <em>Right+Drag</em> rotates the grid. <em>Shift+Right-Click</em> (<a href="cmdAcclKeys.html#cmdAcclKeys">Section 3.4</a>) displays a pop-up menu allowing rotation of the grid by various predefined angles.
+</p>
+<p>
+Whether the Snap Grid is drawn is controlled by the <strong>Show</strong> check-box. Also, if the layout is Zoomed Out (<a href="cmdZoom.html#cmdZoom">Section 2.12.4</a>) the minor and major grid lines may be too close together to be drawn. The minimum pixel distance between grid lines is controlled by the <strong>Min Grid Spacing</strong> value on the <strong>Preferences</strong> (<a href="cmdPref.html#cmdPref">Section 2.10.7</a>) dialog.
+</p>
+<p>
+<strong>Note:</strong> on slow machines drawing the Grid can take noticeable time. Performance can be improved by selecting a larger value for <strong>Min Grid Spacing</strong>.
+</p>
+<p>
+<img src="png.d/bgsnap.png"> <strong>Grid Buttons</strong> on the Tool-bar (<a href="mainW.html#mainW">Section 3.1</a>) can be used to Enable/Disable and to Show/Hide the Snap Grid.

+<p>
+Most windows can be opened, closed, resized, minimized, and moved around the screen. The close, minimize, and zoom buttons are located on the right side of the title bar. Minimizing a window will close the contents of the window, but store a reference to it in the Task bar. Closing a window will make it disappear completely (so you may be asked to save your changes first). To move a window, click on the title bar and drag the window where you want it.

+The term Shortcut key refers to specific key combinations which are used to accomplish an action which otherwise would be accomplished by moving a MOUSE and /or selecting from a Menu. Shortcut keys are often key combinations consisting of the letter key pressed along with the Alt or Ctrl key.
+</p>
+<p>
+Instead of using the menus or the buttons on the <strong>Tool-bar</strong> (<a href="mainW.html#mainW">Section 3.1</a>), most <em>XTrackCAD</em> commands may be invoked through use of Shortcut keys.

+The <code>RETURN</code> key has the same effect as pressing the <strong>OK</strong> button on the current dialog.
+</dd>
+</dl>
+<p>
+
+</p>

+The <code>ESCAPE</code> key cancels the current command. All selected tracks are unselected. The <strong>Properties</strong> (<a href="cmdDescribe.html#cmdDescribe">Section 2.2.13</a>) or <strong>Select</strong> (<a href="cmdSelect.html#cmdSelect">Section 2.2.16</a>) command becomes the current command.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+The <code>F1</code> key opens the Help page for the currently selected command. <code>Shift+F1</code> opens the Contents Help Page.
+</dd>

+The <code>PAGE UP</code> and <code>PAGE DOWN</code> keys will zoom out or zoom in.

+<dl><dd>
+The <code>ARROWS</code> key will pan the canvas right, left, up and down.

+<dl><dd>
+The <code>DELETE</code> or the <code>BackSpace</code> key invokes the <strong>Delete</strong> (<a href="cmdDelete.html#cmdDelete">Section 2.4.4</a>) command.

+<h1><a name="cmdAcclKeys"></a>3.4 <a name="i0"></a>Mouse Actions</h1>
+<p>
+<em>XTrackCAD</em> uses the left and right mouse buttons when manipulating tracks and other objects on the layout. Their meaning depends on the particular command:
+</p>
+<p>
+<em>Select Command</em>
+</p>
+<p>
+The <em>Select</em> command actions are affected by the mode selected in <strong>Options-&gt;Command-&gt;Select</strong>. Note - Objects in a Module Layer are selected and deselected as a group.
+</p>
+<dl><dt>
+<em>Left-Click</em>
+</dt>
+<dd>
+Single Item Mode -&gt; Selects one object at a time, deselects other objects. Add Item Mode -&gt; Adds unselected objects, deselects if the object is already selected. If the click is on an area without objects and <strong>SelectZero</strong> is set, all objects are deselected.
+</dd>
+<dt>
+<em>Shift-Left-Click</em>
+</dt>
+<dd>
+Selects all connected tracks from the one clicked up to the next selected item in each direction.
+</dd>
+<dt>
+<em>Ctrl+Left-Click</em>
+</dt>
+<dd>
+Single Item Mode -&gt; Adds an object to the selection, deselects if the object is already selected. Add Item Mode -&gt; Selects just this item and deselects other objects. If the click is on an area without objects and <strong>SelectZero</strong> is set, all objects are deselected.
+</dd>
+<dt>
+<em>Double-Left-Click</em>

+</dd>
+<dt>
+<em>Left+Drag</em>
+</dt>
+<dd>
+Single Item Mode -&gt; Selects all objects in an rubber-banded area and deselects all others. Add Item Mode -&gt; Adds items in the rubber-banded area.
+</dd>
+<dt>
+<em>Shift+Left-Drag</em>

+</dd>
+<dt>
+<em>Right-Click</em>
+</dt>
+<dd>
+Displays a pop-up menu of context commands (in Select, Move, Modify and Rotate commands). If some track is selected, the menu has operations to perform on it, if not, it will have a command context menu.
+</dd>

+<h1><a name="faqsTransfer"></a>A.1 Moving from Design to Roadbed <a name="i0"></a></h1>
+<p>
+<strong>Your design is complete and your now ready to lay track. How do you go from the computer screen to the roadbed?</strong>
+</p>
+<p>
+The best way to move your design from computer to roadbed is to print out a full scale copy (or portions) of the layout. During the print process the orientation of the print grid can be adjusted so the printout will line up with the tracks.
+</p>
+<p>
+If you have cut-sheet printer (like a laser or ink-jet) set the Ignore Page Margins toggle on the print dialog. Normally there is an unprintable margin around the edge of the page and <em>XTrackCAD</em> only prints on the printable area, which means you would have to trim or overlay the pages. Setting the Ignore Page Margins toggle makes <em>XTrackCAD</em> ignore this margin so you can just abut the paper. Also, turn on Print Roadbed Outline and set your roadbed width.
+</p>
+<p>
+For large scale printouts, the ability of many platforms to print as PDF is very helpful. Commercial printers can oftem print very large strips of paper.
+</p>
+<p>
+Once you have a full scale print-out of your layout (or portion, if you have a larger layout you don't want to do it all at once) you need to transfer this to the roadbed. Here's two methods that can be used:
+</p>
+<ul><li>
+Use a spray adhesive (such as 3M Super 77) to glue the print-out to the roadbed. This is very messy, takes more glue than expected and is very unforgiving of mistakes. You may want to use this method only for small sections of very complicated track-work.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+Tape the print-out to the roadbed then using a tracing wheel (available at Sewing shops), trace the center-line of the track and roadbed outline. At this point consider places when you'll want to widen the roadbed to support signals, switch machines, joints etc.
+</li>
+<li>
+Some users have reported that they successfully used the DXF export to get a file into Computer Controlled Machines that can cut out trackbed.
+</li>
+</ul>

+<h1><a name="faqsHotBar"></a>A.2 Hot Bar Items Missing!</h1>
+<p>
+<strong>After installing XTrackCAD the Hot Bar is not active; the arrows to the left and the right of the Hot Bar are a grey colour instead of black, the Hot Bar is blank and also does not scroll.</strong>
+</p>
+<p>
+There's nothing wrong, you just need to load a track or structure Parameter file. Open the <strong>Parameter dialog</strong> window (<strong>File&gt;Parameter</strong>) then click on Browse. A list of <code>*.xtp</code> files with names like <code>atlasn55.xtp</code> should appear. Select whichever file or files are appropriate for your needs then click the OK button. Click OK on the Parameter File dialog and you should now have objects displayed on the Hot Bar.
+</p>
+<p>
+Notes:
+</p>
+<ol><li>
+Only elements that fit the selected scale are available in the Hot Bar. Thus if you're sure the parameter file has been loaded via the <strong>File&gt;Parameter</strong> dialog, make sure the correct scale has been selected for the layout (<strong>Options&gt;Layout</strong>).
+<p>
+
+</p>
+
+</li>
+<li>
+If a long list of parameter files is selected, movement within the Hot Bar can be slow. If you right-click on the Hot Bar, a list of available parameter sets is shown. By <em>Left-Click</em>ing the desired parameter set, the Hot Bar is immediately scrolled to the first element in that parameter set.
+<p>
+
+</p>
+
+</li>
+<li>
+When a new layout is created or when <em>XTrackCAD</em> is started for the first time, the scale of the layout defaults to N scale. Do not forget to change the scale in order to see tracks from other scales in the Hot Bar!

+<h1><a name="faqsPrototype"></a>A.3 Unable to Add Cars to Inventory!</h1>
+<p>
+<strong>After installing</strong> <em>XTrackCAD</em> <strong>you're unable to add cars to the Car Inventory list; a message stating "No Car Prototypes are defined...." appears when you attempt to add cars to the Car Inventory list.</strong>
+</p>
+<p>
+There's nothing wrong, you just need to load a Prototype definition file.
+</p>
+<p>
+<em>XTrackCAD</em> includes a parameter file which defines many common North American Prototypes. The file is named <code>protoam.xtp</code>. It's loaded into <em>XTrackCAD</em> in the same way that a track, structure or car Parameter file would be loaded.
+</p>
+<ul><li>
+Open the <strong>Parameter dialog</strong> window (<strong>File&gt;Parameter</strong>) then click on Browse. Scroll through the list of <code>*.xtp</code> files to locate the file named <code>protoam.xtp</code>. Select this file then click the OK button. Click OK on the Parameter File dialog to complete installation of the prototype file. You should now be able to add cars to the Car Inventory list.
+</li>
+</ul>
+<p>
+Other prototype definitions can be created using the Car Prototype dialog. Refer to <a href="carprototype.html#carprototype">Section 2.9.1.3</a> for detail.

+<strong>How do I join tracks, place turnouts, build a yard etc?</strong>
+</p>
+<p>
+First take a look at the help file. Then try the demos (<strong>Help&gt;Demos</strong> menu). This should answer a lot of questions on how to use <em>XTrackCAD</em>. Please visit <a href="http://www.xtrkcad.org/Wikka/HomePage" target="_blank">The XTrackCAD Wiki</a> if you need help, especially if you find the documentation unclear or think some area needs improvement.

+<p>
+<strong>Active Endpoint</strong> - when placing a turnout, the endpoint which is used as a 'handle' when moved along other tracks.
+</p>
+<p>
+<strong>Auto-connect</strong> - when placing turnouts (<a href="cmdHotBar.html#cmdHotBar">Section 2.7</a>) and creating parallel (<a href="cmdParallel.html#cmdParallel">Section 2.1.5</a>) tracks, the new track will automatically be connected to other tracks if the tracks are aligned properly.
+</p>
+<p>
+<strong>Block Gap</strong> - provides control by dividing the layout into electrically isolated blocks, where trains can be slowed or stopped by lowering or cutting the power to a block. Dividing a layout into blocks also permits operators to run more than one train on a layout with much less risk of a fast train catching up with and hitting a slow train. Blocks can also trigger signals or other animated accessories on the layout, adding more realism (or whimsy) to the layout. Three-rail systems will often insulate one of the common rails on a section of track, and use a passing train to complete the circuit and activate an accessory.
+</p>
+<p>
+<strong>Cornu</strong> - * Cornu curves are a family of mathematically defined curves that define spirals that Euler spirals and elastica come from. They have the useful property for us that curvature increases linearly along the curve which means the acceleration towards the center of the curve also increases evenly. Railways have long understood that smoothly changing the radius is key to passenger comfort and reduced derailments. The railway versions of these curves were variously called easements, Talbot or Euler spirals.
+</p>
+<p>
+<strong>DXF Format</strong> - Abbreviation of <strong>D</strong>ata <strong>E</strong>xchange <strong>F</strong>ile, a two-dimensional graphics file format supported by virtually all PC-based CAD products. It was created by AutoDesk for the AutoCAD system.
+</p>
+<p>
+<strong>Easement</strong> - special sections of gradually curving track used to connect straight and curved tracks (or two curved tracks). Easements reduce the effects of sudden changes in track curves which can cause derailments. They also look great!
+</p>
+<p>
+<strong>Endpoint</strong> - One of the most important concepts in <em>XTrackCAD</em> is the endpoint. A piece of flex-track has an endpoint at each end. An endpoint has a position and an angle and it can be connected to other endpoints. The endpoints control where the track is placed and how it is connected.
+</p>
+<ul><li>
+Turnouts have several endpoints (normally 3).
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+Turntables have a varying number.
+</li>
+</ul>
+<p>
+<strong>Error Message</strong> - an error message displayed in the Status Bar (<a href="mainW.html#mainW">Section 3.1</a>) accompanied by a beep.
+</p>
+<p>
+<a name="i1"></a><strong>Fixed-track</strong> - These include Turnouts, Sectional tracks and Grouped objects. They are defined in Parameter Files (<a href="cmdPrmfile.html#cmdPrmfile">Section 2.5.7</a>), or created using the <strong>Turnout Designer</strong> (<a href="cmdTurnoutNew.html#cmdTurnoutNew">Section 2.9.9</a>) or the <strong>Group</strong> (<a href="cmdGroup.html#cmdGroup">Section 2.9.4</a>) command. They are selected for placement on the layout using the <strong>Hot Bar</strong> (<a href="cmdHotBar.html#cmdHotBar">Section 2.7</a>) or the <strong>Fixed-Track</strong> (<a href="cmdNewFixedTrack.html#cmdNewFixedTrack">Section 2.1.8</a>) dialog. They can not be directly altered, but can be decomposed with the <strong>Ungroup</strong> (<a href="cmdUngroup.html#cmdUngroup">Section 2.9.11</a>) command and some cases trimed (<a href="splitDivide.html#splitDivide">Section 2.2.17.2.1</a>).
+</p>
+<p>
+<a name="i2"></a><strong>Flex-track</strong> - Flexible sections of track used on a layout. It usually comes in straight, three-foot-long sections which can be bent or shaped as needed. These include Straight, Curved, Easements, Cornu and Bezier tracks. This term is also used for hand-laid track. They are created by invoking the corresponding command and dragging on the layout. <strong>Easements</strong> (<a href="cmdEasement.html#cmdEasement">Section 2.10.4</a>) are created automatically when joining tracks.
+</p>
+<p>
+<strong>Frog</strong> - the place on a turnout track where one rail crosses the other.
+</p>
+<p>
+<strong>Gauge</strong> - The distance between the inside of the heads of track rails. Most real railroads in North America and Europe are built to a standard gauge of 4'-8 1/2". Narrow gauge means rails with a width less than standard gauge. For example, On3 means O scale trains with three scale feet between the rails.
+</p>
+<p>
+<strong>Handlaid</strong> - Track that's built with handmade ties, rail, and spikes.
+</p>
+<p>
+<strong>Helix</strong> - A rising curve which turns around an axis like a corkscrew. Used on multilevel layouts to allow trains to go from one level to another.
+</p>
+<p>
+<strong>Info Message</strong> - an informational message displayed in the Status Bar (<a href="mainW.html#mainW">Section 3.1</a>).
+</p>
+<p>
+<strong>Object</strong> - an item on the layout, such as a track segment, table edge, line, note or text.
+</p>
+<p>
+<strong>Points</strong> - the part of the Turnout that moves to select a path.
+</p>
+<p>
+<strong>S-Curve</strong> - (aka <strong>Reverse Curve</strong>) a curve which bends in one direction and then the other, forming an S-like shape, without any appreciable length of straight track between the two curves
+</p>
+<p>
+<strong>Sectional Track</strong> - prefabricated track which cannot be bent, split or changed. A type of <strong>Fixed-Track</strong>.
+</p>
+<p>
+<strong>Selected Endpoint</strong> - when selecting track for various reasons the selected endpoint is the one closest to the selection point.
+</p>
+<p>
+<strong>Tangent</strong> - A line, curve, or surface meeting another line, curve, or surface at a common point.
+</p>
+<p>
+<strong>Track Segment</strong> - any piece of flex-track, turnout or sectional track.
+</p>
+<p>
+<strong>Turnout</strong> - A piece of track that allows a train to go from one track to another. Called a switch on a real railroad. Referred to by number. For example, a no. 6 turnout spreads one unit for each six units of travel measured from the frog (the point at which two rails join to form a V).
+</p>
+<p>
+Turnouts are a type of 'Fixed-track' which includes Sectional Tracks and Grouped Objects.
+</p>
+<ul><li>
+In <em>XTrackCAD</em>, <em>Turnouts</em> also include sectional Tracks, crossings and forms of prefabricated (non-flex) track.
+</li>
+</ul>
+<p>
+<strong>Turnout Frog</strong> - the place on the turnout track where one rail crosses the other.
+</p>
+<p>
+<strong>Turnout Number</strong> - the ratio of the number of units along the center line of a switch frog traversed for each unit the frog spreads to the sides. A No. 4 frog diverges 1 unit for every 4 it moves ahead; a No. 6, 1 for every 6 units. Although we usually refer to a turnout or switch number, in reality the measurement is for the frog.
+</p>
+<p>
+<strong>Turnout Points</strong> - the part of the Turnout that moves to select a path.
+</p>
+<p>
+<strong>Unconnected Endpoint</strong> - an endpoint which is not connected to another.

+<h1><a name="controlElementScripts"></a>B.3 Control Element Scripts and the Model RR System's Dispatcher</h1>
+<p>
+Notes about control element scripts and the Model RR System's Dispatcher program in OpenLCB mode:
+</p>
+<p>
+When using the Model RR System's Dispatcher program in OpenLCB mode to create CTC panels, the panel elements can have their LCC event IDs automatically populated from the information in the XTrackCAD file, if the proper syntax is observed.
+</p>
+<p>
+A LCC event id is a 64-bit number, represented as eight pairs of hexadevimal digits (0-9, a-f/A-F) separated by periods (.). Each pair represents one 8-bit byte of the event id. This event id is either produced by a sensor or logic element or is consumed by a control/device or a logic element.
+</p>
+<p>
+For blocks the occupency script contains a pair of LCC event ids, separated by a colon (:). The first LCC event id is produced by the occupency detector when the train enters the block and the second LCC event id is produced by the occupency detector when the train leaves the block.
+</p>
+<p>
+For switchmotors the point sense script contains a pair of LCC event ids, separated by a colon (:). The first LCC event id is produced by the point sensor when the points are aligned in the "normal" position (typically aligned to the main) and the second LCC event id is produced by the point sensor when the points are aligned in the "reverse" position (typically aligned to the spur). The normal and reverse script each contain a signal LCC event id. These events are produced by the CTC Panel when the control point Code button is pressed (clicked) and are consumed by the switch motor.
+</p>
+<p>
+For signals, the aspect name is a space separated list of the color(s) of the signal heads from top to bottom and the aspect script is a LCC event id that is consumed to produce that aspect. Presumably, the LCC event id is produced by a logic element (presumably a mast group in a Tower-LCC or similar device) or virtual track circuit in a Tower-LCC or similar device.

+The definition you're attempting to create uses the same name as an existing definition. Saving the definition with the same name will cause <em>XTrackCAD</em> to replace the existing definition, making the existing definition inaccessible. If the previous definition must be preserved, then choose a different name for the new definition. If necessary, the <strong>Custom Management</strong> dialog can be used to change definition names.

+<p>
+Version 5.x.x of XTrackCAD introduced many enhancements an additions including Layout Control Objects, Cornu Tracks and Bezier Tracks and Lines. It is upward compatible from earlier versions but if the new objects are included in layouts, the files will not be readable by earlier versions.
+</p>
+<p>
+Users should take a backup of thier Layout files if they will want to use the previous level of code before opening them.

+<p>
+<strong>Updated Titles</strong>
+</p>
+<p>
+<img src="png.d/updttl.png">
+</p>
+<p>
+Version 2.0.0 of <em>XTrkCad</em> introduced a change in the way Turnouts and Structures are named. The new method splits the title into 3 parts: Manufacturer, Description and Part Number.
+</p>
+<p>
+To help you when upgrading to the new version, when loading an old <em>XTrkCad</em> layout file, <em>XTrackCAD</em> detects if the layout uses Turnouts and Structures that have titles in the old format. If so this dialog is displayed which allows you to change the titles in your layout to the new format.
+</p>
+<p>
+The title of each different type of Turnout is collected and presented in this dialog. Simply select the Turnout on the list that matches the one displayed and click 'Update'. Repeat for each type of Turnout in your layout.
+</p>
+<p>
+If there is no matching Turnout, click on Ignore. The Turnout will retain the old name as the Description, with a blank Manufacturer and Part Number.
+</p>
+<p>
+Click Cancel to continue loading the file without updating the titles.
+</p>
+<p>
+If you Save your file without updating all the titles you will not be able to update the titles later.
+</p>
+<p>
+If you are looking at old files without making changes then Click on Cancel to load the file without Updates.
+</p>
+<p>
+Not updating the titles prevents the customization of the way titles are presented in various lists and on the layout. Basic operation of <em>XTrackCAD</em> is not affected.

+<p>
+<strong>Internationalization</strong>
+</p>
+<p>
+Internationalization or the ability to localize <em>XTrackCAD</em> for use with various languages was adopted during this version upgrade. <em>XTrackCAD</em> is now available with balloon help and daily tips written in US English, Finnish and German. The <em>XTrackCAD</em> development team welcomes anyone who wishes to volunteer with translation of various support files. Let them know by submitting an offer to assist to the <em>XTrackCAD</em> <strong>Feature Tracker</strong> located at the <a href="http://sourceforge.net/tracker/?group_id=151737&amp;atid=781981" target="_blank"><em>XTrackCAD</em> Fork Project Site</a> or the <em>XTrackCAD</em> <strong>Wikka Wish List</strong> located at the <a href="http://www.xtrkcad.org/Wikka/WishList" target="_blank"><em>XTrackCAD</em> Wiki: WishList</a>.
+</p>
+<p>
+<strong>Minor Fixes and Enhancements</strong>
+</p>
+<ul><li>
+Thanks to Martin Fischer, the Button Bar has a much cleaner and sharper look.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+Several selections within various Option Menus (Layout, Display, Command and Preferences) have been re-arranged. In some case the order or grouping of menu items changed. In other cases menu items were move to a different menu; still within the sub-set of Option Menus. Our hope is that we've made it easier to locate parameter settings that in past were difficult to locate.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+An new option that allows <em>XTrackCAD</em> to automatically re-open the last layout file has been added to the <strong>Options&gt;Preferences</strong> menu. For detail refer to the &#8216;On Program Startup&#8217; item found in <a href="cmdPref.html#cmdPref">Section 2.10.7</a>.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+Significant updates were made to the Atlas N and HO scale parameter files. Diesel engine and freight car information is now contained in four separate parameter files; Atlas HO Scale Cars (<em>atlascho.xtp</em>), Atlas HO Scale Diesel Engines (<em>atlaseho.xtp</em>), Atlas N Scale Cars (<em>atlascn.xtp</em>) and Atlas N Scale Diesel Engines (<em>atlasen.xtp</em>).
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+Twenty-one prototypes were added to the American Prototype parameter file (<em>protoam.xtp</em>). The additional prototypes are;

+<em>XTrackCAD</em> users reported difficulty when attempting to activate grid lines in version 4.02. The problem was noticeable only on new installations. A default grid size of zero was found to be the cause of the problem. The default grid size has been changed to 1 thus eliminating the problem.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+A small bug preventing Zooms of less than 1:1 (Refer to <a href="cmdZoom.html#cmdZoom">Section 2.12.4</a> for detail.) was accidentally introduced in version 4.0.1. This problem has been corrected in version 4.0.3.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+When new scale definitions were added to XTrkCad 4.0.2, a small bug broke the file format for some scales (eg., N UK). This problem has been corrected in version 4.0.3.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+Some users of the Linux based application reported the <em>Sticky Commands</em> menu would exceed screen length. Spacing between <em>Sticky Commands</em> options has been improved in order to prevent this problem.
+</li>
+</ul>
+<p>
+
+</p>
+<ul><li>
+We've no idea when certain demo's broke however thanks to the work of Mikko Nissinen, many broken demos are now fixed.
+</li>
+</ul>
+<p>
+
+</p>
+<p>
+<strong>Name Change</strong>
+</p>
+<p>
+With release of this version of <em>XTrackCAD</em> there's been a subtle change in the spelling and punctuation of the applications name. From this version forward, the application will be know as <em>XTrackCAD</em>. Please note the spelling and capitalization of the name.
+</p>
+<p>
+Why was the name changed? This release gives <em>XTrackCAD</em> developers an opportunity to included a much sought after feature; Internationalization (Through i18n). On the surface this doesn't sound that big however having the ability to internationalize or localize the product has great advantages for all users. Not only is there great potential for the application to become available to a larger audience, our hope it that the developer pool will expand which should result in more features being added to the application.

+<p>
+<strong>Check-point Files</strong>
+</p>
+<p>
+Version 4 of <em>XTrkCad</em> introduces a new way of handling check-point files. This will allow resuming your work after a system crash much easier than before.
+</p>
+<p>
+If you start <em>XTrkCad</em> V.4.0.x the first time after an upgrade from a earlier version, a pop-up with the question: "Program was not terminated properly. Do you want to resume working on the previous track plan?"
+</p>
+<p>
+Select "Ignore" only if you're sure that the work from your last session has been correctly saved. If uncertain or restarting after an earlier failure select "Resume".
+</p>
+<p>
+
+</p>
+<p>
+<strong>Help System</strong>
+</p>
+<p>
+The built in help system has been converted to a much more flexible and widely used HTML format. With many new graphics and extensively rewritten text the help information is now up-to-date with recent development.
+</p>
+<p>
+<strong>Layer Colour Settings</strong>
+</p>
+<p>
+Your personal layer color settings are now stored in your preferences. This allows you to apply the same settings to other layouts you design.
+</p>
+<p>
+<strong>Parameter Files Updated</strong>
+</p>
+<p>
+Thanks to Ralph Boyd, Dwayne Ward, Casey Sterbenz and others, many new and updated parameter files were added to this release.
+</p>
+<p>
+<strong>Wheel mouse</strong>
+</p>
+<p>
+The wheel on a wheel mouse can now be used to zoom in and out on a layout design.

+<p>
+<em>Preamble</em>
+</p>
+<p>
+The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too.
+</p>
+<p>
+When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things.
+</p>
+<p>
+To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it.
+</p>
+<p>
+For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.
+</p>
+<p>
+We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software.
+</p>
+<p>
+Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations.
+</p>
+<p>
+Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all.
+</p>
+<p>
+The precise terms and conditions for copying, distribution and modification follow.
+</p>
+<p>
+GNU GENERAL PUBLIC LICENSE
+</p>
+<p>
+<strong>TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION</strong>
+</p>
+<p>
+0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you".
+</p>
+<p>
+Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does.
+</p>
+<p>
+1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program.
+</p>
+<p>
+You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee.
+</p>
+<p>
+2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions:
+</p>
+<dl><dd>
+a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.)
+</dd>
+</dl>
+<p>
+These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.
+</p>
+<p>
+Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program.
+</p>
+<p>
+In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License.
+</p>
+<p>
+3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following:
+</p>
+<dl><dd>
+a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.)
+</dd>
+</dl>
+<p>
+The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable.
+</p>
+<p>
+If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code.
+</p>
+<p>
+4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.
+</p>
+<p>
+5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it.
+</p>
+<p>
+6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License.
+</p>
+<p>
+7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program.
+</p>
+<p>
+If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances.
+</p>
+<p>
+It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice.
+</p>
+<p>
+This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.
+</p>
+<p>
+8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License.
+</p>
+<p>
+9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.
+</p>
+<p>
+Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation.
+</p>
+<p>
+10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally.
+</p>
+<p>
+NO WARRANTY
+</p>
+<p>
+11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+</p>
+<p>
+12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+</p>
+<p>
+<strong>END OF TERMS AND CONDITIONS</strong>
+</p>
+<p>
+<strong>How to Apply These Terms to Your New Programs</strong>
+</p>
+<p>
+If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.
+</p>
+<p>
+To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.
+</p>
+<dl><dd>
+&lt;one line to give the program's name and a brief idea of what it does.&gt; Copyright (C) &lt;year&gt; &lt;name of author&gt;
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+</dd>
+</dl>
+<p>
+Also add information on how to contact you by electronic and paper mail.
+</p>
+<p>
+If the program is interactive, make it output a short notice like this when it starts in an interactive mode:
+</p>
+<dl><dd>
+Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details.
+</dd>
+</dl>
+<p>
+The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program.
+</p>
+<p>
+You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names:
+</p>
+<dl><dd>
+Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker.
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+&lt;signature of Ty Coon&gt;, 1 April 1989
+</dd>
+</dl>
+<p>
+
+</p>
+<dl><dd>
+Ty Coon, President of Vice
+</dd>
+</dl>
+<p>
+This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License.
