Is it just me or the sphere primitives have non planar quads ? Or is the sphere distorted to allow for planar quads ? Why where the sphere done in this way instead of the usual (full quads with triangles on the poles) or (all triangles) ? I hope (...) (25 years ago, 5-Apr-00, to lugnet.cad.dev)

Since the BFC discussion has everything to do with performance improvement, I would like to propose the following changes to the primitives: - 4-4disc.dat - 2-4disc.dat Remove the point which lies in position (0,0,0), because it's NOT required and (...) (25 years ago, 5-Apr-00, to lugnet.cad.dev)

(...) I'd like to have all parts compliant by making a second copy of the primitives that can't be inverted instead of using "0 INVERSE" commands. Leonardo (25 years ago, 5-Apr-00, to lugnet.cad.dev)
