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)

(...) I've always understood it is: X positive is right X negative is left Y Positive is bottom Y Negative is top z Positive is back z negative is front In fact you can show this by adding a brick in MLCad and moving it around, watching how the X, Y (...)
