Comment 13 for bug 192923

Yes, the cutting plotters do interpred the SPLINEs. RoboMaster doesn't
like to re-edit the SPLINEs and crashes if you attempt to move a control
point, but it did this for DXF files created by other exporters too. I
think this crash is a result of RoboMaster expecting only the subset of
SPLINEs that it is able to create, but I need someone more mathy to
prove that.

Are you at all skilled in C++? There was a generalized DXF input/output
written for GSoC a few years back. It went a long way toward solving the
problem, but wasn't integrated because of some security issues, iirc. I
seem to remeber that it was even able to render 3D DXFs into 2D for import.
