Polypen division by zero #238

Closed Nocturael closed 8 years ago

Nocturael commented 8 years ago

In 1.2.0 beta 2, when I try to use the Polypen on a certain mesh target, I get an error message and all vertecies get hidden. Sadly, I have not yet managed to reproduce the bug with another mesh or isolate the conditions of the problem.

@Nocturael, that model likely has an edge with zero length (the two endpoint vertices are at the same location). the above fix should fix polypen from throwing exceptions. please let me know if you still get that error. thanks!

That fixed it, thanks.
