Hi, I'm a complete newbie so please excuse my question. I have created a mechanic piece in Autocad 2004 that contains extruded circles, subtracted solids, ... I would like to then import the model in 3dsmax but when I import the dwg or the 3DS file the extruded circles only have 12 facets : doesn't look like a cylinder ! how can I export the real model (smooth), real circles, cylinder ... ? Thank you very much ! William
