(...) If you use a 3D card then the speed increase from BFC becomes negligible, I've tried to activate BFC on LeoCAD and it didn't show a big difference with the current library. Keep in mind that the current cards (except the newer GeForce) have a (...) (25 years ago, 6-Apr-00, to lugnet.cad.dev)

Good news for Autocad part developers ! My stl2dat converter now reads binary stl files. It recognises binary files automatically. I also introduced a new option to set the origin, because some cad-cam programs can only produce stl files where all (...) (25 years ago, 6-Apr-00, to lugnet.cad.dev)

Are anybody currently working on the Star Wars Battle Droid arms? I would like to use these in a model, and would be quite happy with some simple mock ups. Thanks! Fredrik (25 years ago, 6-Apr-00, to lugnet.cad.dev)
