When I import 3d models containing curves from autocad 2008 to 3dmax 2009, the curves don't come properly, they are jagged and there's no any smoothness..,I tried traditional ways in autocad and 3dmax but no solution.
In autocad I made higher (arch. and segments smoothness, segment in a polyline curve and rendered object smoothness).
In max I tried to change the smoothness settings in the import dwg dialog when i import the 3d object from autocad.
Anyone has any suggestion??
