Intersect fails to produce a complete upper curve between the orange cylindrical object and the green panel. Nudging this sometimes resolves this issue. However I have seen it many times before with various geometries.
Hi @David53 (and anyone else having issues with intersections!), I’m new at McNeel and will be working extensively on the intersectors (curve-curve, curve-surface, surface-surface, whatever). Please don’t hesitate to @ me if you run into trouble, it will be a big help.
