Chris, When I display this DAT file in MLCAD, I get a couple of "bowties". I've taken the liberty of finding the errant lines and providing solutions for them. 0 4 16 15 7 -10 18.72 6.03 -10 14.93 15.68 -10 12 14 -10 4 16 18.72 6.03 -10 15 7 -10 (...)

(...) You'd have to ask James these questions. Only he would know. It *looks* like the non-planar quads could be a rounding error, or rounding limitation, since he used just 2 decimal places. Steve (25 years ago, 5-Apr-00, to lugnet.cad.dev)

I've got a little question. Why are you working so hard on BFC. The rendering in Ldraw, L3lab, MLcad,.... is already very fast. Is the speed improvement gained with BFC supposed to provide the extra time, so you can turn an model in realtime, with a (...) (25 years ago, 5-Apr-00, to lugnet.cad.dev)
