In applying a boolean difference operation to a convex surface, distortions appear in the surface surrounding the cutout, causing issues with surface smoothness. An example of this is below, along with the source file. This geometry doesn’t seem to be prone to any of Rhino’s known Boolean limitations (coincident/overlapping edges, etc), so I can’t think of why this would be happening. Thank you.
