I have a drawing I need to export as a DXF, a single closed Polyline, but the arcs in it have to be converted to segmented polylines. The custom CAM software and CNC cutter I'm writing to simply won't take arcs no matter how hard I try.

I've been able to use DraftSight on simpler non-arc'd drawings to convert the bugged non-merged SW DXF exports into closed polylines, but DraftSight doesn't seem to have a built-in feature for segmenting an arc.

Thanks
