Unroll Brep Bug - Curve list reverses!

Unroll Brep works… but reverses the list of curves for some breps?
Is this a bug ? Can it be fixed? or is there a workaround using a Path Mapper - that is to only reverse those branches that are in the wrong order?

Can you share an example model and script?

I cant, the geom is under an NDA and I haven’t got time to test configurations out until I find a fail situation.


I hope I find an example soon.


I suggest you pay attention to brep face directions. Sometimes if the normal is flipped, curves can be reversed.

How can one flip all surfaces without re ordering them?

I’m not sure I understand. Please share a simple example.
