Pretty simple question:

Revolution-UntrimmedSurf.gh (17.0 KB)
When I revolve a closed curve, the resulting geometry is an “untrimmed surface,” but not the expected “closed brep,” as demonstrated by the capped extrusion.
I would think that “Closed Brep” would be the priority definition of a geometry, as it’s better to know whether you’re working with a brep or a surface. Is there something about this revolution geometry that is making it fail the “closed brep” definition, or does it fit the definition but its “untrimmed surface” label takes higher priority?
