This contour model has a lot of triangles, too many I think for it to let me ungroup it. I got the rubyscript to simplify contours and ran the original topo contours at the default 10° level. Apparently it wasn't enough, because look at the level of detail.
So, any pointers would be helpful to get this to a functional level of simplicity would be helpful.
Task One: Simplify contours...Task Two: Draw contours.... Task Three: Explode Contour Model.... Task Four: Drape roads
Is that right?
