My near-term goals are pretty limited. Beyond processing 2D intelligently and presenting a clean object-oriented interface to 2D entities, my goals are simply to not choke, and to gather information for a single entity all into one place, without trying to process intelligently -- more of a "here it is if you know what to do with it". > I know someone else working on getting 3D usable by FOSS tools by way of a > common open format > available as a standard or defacto standard.

The FreeCAD guys, however, are making progress a bullet-train speed. My first instinct would be to find a way to help them. -dave _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
