- When I export dwg or dxf as 3d choosing only edges in export options dialogue and then try to import this dwg or dxf file into rhino or 3ds max in order all circles could be as real circles (without segmentation) I see that there are a lot of duplicated lines, circles. Here is a simple example of a cylinder created in SU and then imported to 3ds max. See that there are these duplicated lines, circles.
Why is this happening? 2. And by the way as far as I remember it’s not impossible to export it from SU in a way that not only edges were represented in other CAD applications but surfaces (faces) also? Because when in dwg export dialogue I choose edges and faces it exports faces for example of a cylinder as segmented polygons together with edges thar are really curves but not the faces.
