DXF is a hairy format and CAD tools export wildly different subsets. Our parser handles: LINE, LWPOLYLINE, POLYLINE, CIRCLE, ARC, SPLINE (via de Boor sampling). Hatching, dimensions, text, blocks/inserts, layers — all ignored.
If your DXF has extra junk after load: open it in LibreCAD or AutoCAD, delete everything that isn't the cut profile, save as DXF R12 (the most-compatible version). That usually fixes it.
