(...) That looks like a correct mapping to me. Unless I'm mistaken the red and orange are on the same sides in both pictures. The unwrapped boxes are definitely identical and unless you've moved them in one or the other the whole thing is right. Tim (18 years ago, 19-Nov-06, to lugnet.cad.dev, FTX)

As I understand it, LDraw has negative y in the up direction, which is neither right nor left handed, but something else entirely. I don't know that it has a name. James (18 years ago, 19-Nov-06, to lugnet.cad.dev)
