I’ve patched contours, and now have a topo. I’m now projecting building foot prints onto the topo, however when I extrude the buildings won’t cap or become solid because the extrusions follow the topography and are not flat on top. there must be a way through either projection or extrude where the “buildings” are extruded as closed “buildings” that sit on the topo. Anybody who’s worked with rhino and site models have any suggestions?
thanks in advance
