Yea, the cross section method works great, the only downfall is having to figure out a way to texture each road segment once you have a full road extruded. Blender has a really cool system fo making a track and texturing it, I was hoping ac3d did also....since I really dislike blender :P
this is the blender technique.

Lets say I extrude a full road, is there a way to texture all segments without doing each individually?
