AutoCAD allows you to convert entities to polylines, but not during the export. I'd recommend supporting polylines, lines, arcs, and circles only. But you should plan on having to join entities on import, because, as I said, I don't think a lot of CAD packages give the option to join. But, I could be wrong. One thing you should do is recommend v12 dxf or older. The v12 .dxf format does NOT support splines and elliptical arcs, so they are automatically converted to polylines. 3) I don’t think that most 2D CAD programs give you that option.
