at the architecture office I work in I have been experimenting with creating models of sites...I start by using the site plan, creating closed polylines (so I have something to extrude when I bring it into 3ds Max)...3ds Max seems to have a problem with arcs, sometimes they come in correct, but rarely do I get everything to come in correctly. Please help, I am getting good at materials and everything else, this seems like something minor that shouldn't even be happening, advice is greatly appreciated
