I'm trying to get a ".3ds" file and a AutoCAD 2004 ".dwg" file from the ".max" file. I need to import the ".3ds" file into an ArcGIS geodatabase as a 3d multipatch, for use in ArcScene. When I export the file as either a ".3ds" file or an AutoCAD file, the cylindrical shapes become either jagged or squared along the edges.
