Topic: ( C3D 2008 ) Display points by station/offset

[sinc]

The SincpacC3D now includes a STAOFF command, which is basically the same as the old Land Desktop "Display Points by Station and Offset" command.

This tool is pretty critical to surveyors, and I know I'm not alone in wondering what Autodesk was thinking.  Civil-3D has that "Station Alignment to Points" XML report, but it's a pretty sorry replacement - hardly even usable.  This should help fill the gap.   

The code for this involves several classes, so I'm not posting any of it here, but the complete source code is also posted along with a DLL compiled for Civil-3D 2008.  But it uses a variety of design patterns, and is another one that might serve as a good sample for anyone trying to learn C#.

I took the guts of this code and refactored it, then added another command - PT2PROFILE - that will datum-adjust existing points based on any of the profiles in your drawing.

In the process, I created a couple of class hierarchies that illustrate C# keywords like PROTECTED, ABSTRACT, VIRTUAL, OVERRIDE, and NEW, and can serve as a working example for someone trying to learn when, why, and how to use these keywords.
