But it does have 3D entities in the file format. My earlier comments w.r.t. a dxf i/o library reflect both of those statements. :) I don't know much about 3D file formats. I know stl is basically a bag of triangles, and I think stl is also. So while you can communicate a hull, you can't do much more. No parametric information, no material information, no joint information, etc. Not sure about iges, I know pretty much nothing about it. -dave _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
