(...) By candidate, I meant, someone could optiomize it, a place a 0 CLIPPING ON meta-command on it, and get some benefit. If you use enable clipping, but you have no graphic primitives in your file (assuming clipping is stryctly local), than you (...) (25 years ago, 20-Oct-99, to lugnet.cad.dev)

(...) Yes the coded inversion is needed, for one big reason: The clipping-ready parts library must be compatible with non-clipping rendering programs, such as LDraw. So the inversions need to occur in the real commands, not in the clipping-extension (...) (25 years ago, 19-Oct-99, to lugnet.cad.dev)

(...) <snipped stuff about INVERT> I think we're disagreeing about the meaning of 'strictly local'. As you describe the operation of INVERT, it is *not* local. The state of inversion is passed down the file-reference tree. This is not a local (...) (25 years ago, 19-Oct-99, to lugnet.cad.dev)
