Adding code in XTrackCAD is a larger task, so instead I have developed a small standalone program that only reads XTrackCad files and enable viewing. (Windows only)
XtrackViewer will create elevations based on XTrackCAD file data and will try not to skew turnouts. Elevation values may therefor differ from elevations in XTrackCad.
Slope is calculated at centerline. XTrackCAD I believe calculate inner rail slope.
As with XTracCAD lengths and radius are two-dimensional.
( I am working of a new version with improved graphic. You might want to check it out on sourceforge
