Help! I'm trying to take information from AutoSurf/AutoCAD 12 to 3D Studio via AutoVision. However the poly mesh unhide does not produce very good geometry to render. Anyone come across this? Any suggestions? Seems it should do a better job than what is does – are there some optimum settings I should be tring to use? I need an easy solution if possible since this is for rapid prototyping of parts. I'd be glad to send renderings of what we got if that will help. Thanks!
