Hi, I've got a reworked version of LSynth with a major problem... I cannot figure out how to control the twist of the cross section. I use bezier curve to created the nicely curved set of points, and compress it by tossing out points until the angle (...) (18 years ago, 24-Nov-06, to lugnet.cad.dev)

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)

(...) I agree with Tim. It looks fine to me. If there were any mirroring going on, then either the orange and red would be swapped on the unwrapped box, or the green and grey would be swapped. The picture in LDView has a rotated camera angle (...) (18 years ago, 19-Nov-06, to lugnet.cad.dev, FTX)

(...) Google uses the right handed system but indeed rotated by 90 degrees, LDraw also uses the right handed system but 180 degrees rotated. It should not matter how you show the model, the coordinates are interchangeable, but if you want to use (...) (18 years ago, 19-Nov-06, to lugnet.cad.dev)

(...) 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)

Hi, Here's my box test model in SketchUp. (The above model is the same model unfolded.) (URL) When I export this model to a .dat and open it in LDView, the green side is the top-view, blue is the front view (as expected), and I would expect the (...)
