Yeah DWG or DXF is a must for me, im fed up of playing with PDFs (and still no groups, ggrrr!!!!). I think the time spent making a dxf importer would be well worth it in terms of attracting more folks to moi. most other software worth its salt has a dwg importer these days, isn't there a generic one that someone has made that simply translates the lines and coordinates? Im mean in terms of 2D from the outside it would seem like its just basic lines and arcs, certainly compared to nurbs complexity. I think holding off on this is a big oversite to be honest but its michaels call.
