(...) When it finds that any face of a primitive needs to be inverted. We would have to fix the current primitives so that all faces are pointing to the same direction. Take a look at the sphere primitive for example, it has faces pointing inside (...) (25 years ago, 6-Apr-00, to lugnet.cad.dev)

(...) The primitives should be the first thing fixed, in any case. :) I think it would be safe for the cleanup program to assume that primitives are BFC-ready. Which could be a help for automatic cleanup of part files. (...) Some technical points: (...) (25 years ago, 6-Apr-00, to lugnet.cad.dev)
