The DXF is a proprietary file format of the AutoCAD system used for transferring geometry and drawing information although many other types of tools support this format too. It is the primary format for transferring basic geometry data. However, it has limited support for NURBS surfaces.
Note: AutoCAD locks any DXF files it has open. Consequently, PolyCAD cannot open any exported files from AutoCAD until these are closed.
