LDraw Pattern Creator/ LDPattern Help

[Philippe Hurbain]

It works fine on flat patterns (e.g. torso, flag), but if you project the result onto a formed surface, these quads possibly are broken back to triangles.

I agree with you, it maybe quite annoying. I met this problem while doing this pattern. I solved the issue by changing colors of a few triangle pairs that I wanted to be assembled together. That's a trick useful to control behaviour even in "normal" use, for example to keep symmetry in the middle of a shape issued from LDD.
