I’m just continuing last year’s thread:
I’ve been experiencing the same issues as described but with other curve shapes. In some cases when the polycurve is straight, I managed to re-create a single curve from the start point and end point, but for polycurves containing more than one line in different directions, “An internal error has ocurred” shows.
Does anyone experienced the same issue and, the most important, already solved that issue?
I’m thinking what @TSF said could be the problem.
I’ll give it a try.
Thanks in advance!
