I created a closed object by Sweep2 (Periodic Curves) and 1 Section Curve(Periodic). The result is a Untrimmed Periodic Surface. Then I have a Closed Brep created by various Intersections/Difference. Now: when I try to UNION these together it doesn't work. Any reason? I baked them and Union in Rhino (but I had to change the Absolute Tolerance from 0.001 to 0.01) and it works , why not in GH? Is there a difference between "Untrimmed Periodic Surface" and "Brep" when Union in GH?
Thank you in advance.
