I can’t get unroll srf to work it mirror inverts everything.
Also Unroll surface produced wrong results on objects that were trimmed, in that case it ignores the trim and extends the curves as if the surface was not trimmed. I had to shrink trimmed surface to get around this.
Here’s a file, pretty simple but rhino one won’t give correct results on a trimmed surface and it constantly inverts the placement contrary to the labels.
