Hi all, I am updating the train poster and need some help, or actually some files.

A sincere thanks to all of you. Your comments made me go back over (again) my export code, and I found an error. Now it works as expected. I was getting funny rotations because I mis-ordered the elements of the transformation matrix, duh. Seems (...) (18 years ago, 20-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)
