What about a flag for default behavior? I've been coding to ignore ones with default rotations, but there are plenty of parts (especially slopes) that need a (-1 0 0 0 1 0 0 0 1) rotation applied when reflected front-to-back and it would be nice to (...) (20 years ago, 24-Jun-04, to lugnet.cad)

(...) I don't think so. 5 is for keeping track of which parts we've looked at, not which ones to ignore when your run your mirror program. Eventually I think we'll remove all the ones marked with a 5 from the MIRROR.INI file. (And that includes the (...) (20 years ago, 24-Jun-04, to lugnet.cad)

(...) IMO there *is* value to knowing that the proper exception matrix is indeed an exception rather than coincidentally the same as the default matrix. If the 5 is not the place for this, there should be a new flag for it. It's especially important (...) (20 years ago, 24-Jun-04, to lugnet.cad)

(...) Sure, but you still haven't convinced me there's any difference between a 2x2 brick and a 2x2 slope brick. I must be getting senile in my old age, because I just don't get it. Anyhow, use 55 if it makes you happy. We'll figure out what to do (...) (20 years ago, 24-Jun-04, to lugnet.cad)
