I've been using an Othermill desktop CNC mill and a cheap Chinese laser engraver/cutter for prototyping small pieces, but the most software i've been using for simple 2D & 2.5D CAM work on a MAC only takes SVG files for input. The workflow I have now is export to DXF, then convert to SVG in Inkscape, but it seems to introduce errors. Is it possible to add SVG export to Vectorworks. SVG import would be nice as well for editing files from Thingiverse etc.
