| | | | 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 (...)

| | | | | | (...) 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)

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)
