Hi Anthony, I also updated the converter program ( http://moi3d.com/download/3dmCurves2DXF.zip ) to write this additional flag as well, so if that circle works then grab this new version.

Yes, when I get to this point for version 2 I want to have several options for DWG/DXF export, whether to export as splines, use arc and line entities, or break things into polylines.
