Matt,
If you can't find one that works for you, can you E-mail me the drawing with the picture of X-section you want to create ? I am sure I can help you.
I can create your target X-section (or any X-section Template) in less than 10 minutes using the Visual Subassembly Editor without any VB programming, and of course the resulting corridor model for all plotted sections and quantities. You can find my e-mail address at www.cadtown.com. I can also send you the Beta version of the software and tutorials for free...
Peter,
