Andrew, I think you've missed the point- with the 'lines'; C3D actually does import lines very well. If I draw exactly the same drawing (in Intaglio)- a intersected square and circle, save as an svg, then import into C3D and then extruding the drawing, I get this;
Whereas, if I draw the same image in QCad and then import that into Cheetah3D, I get this;
(notice that the rectangle is missing!)
If I add a solid fill (which I did to get a solid object in Intaglio in the first image above) to the QCad drawing, I can't even get an option to extrude at all.
These are my findings, which suggest that there is a problem with the SVG file that QCad is outputting.
