"This tool, in short, provides a way to take digital cross sections, specify an accompanying horizontal alignment and create a surface."

I didn't have time to watch the video, but it sounds like a corridor.....?

Sounds like but isn't......if you have been supplied with, I guess, a 3rd party's drawing containing dumb CAD polylines You can recreate an alignment in C3D and from there can "reverse engineer" the cross sections to create a surface.

 

As mentioned in the blog "...This tool serves a bit of niche role.." but this particular niche is one that happens to me very regularly.

 

This link demonstrates another more manual approach http://advsurveying.com/advcivil/?p=71
