I've imported a Solid Edge assembly, and one of the parts has surfaces in it. The surfaces import and are all grouped together with the solid body as the same KeyShot part. I can't hide/delete the surfaces without going back to Solid Edge intentionally changing the colors of the surfaces and reimporting. These parts are using the default Solid Edge colors. Surfaces are magenta and parts are gray in Solid Edge.
Do not use the "Beta" importer. If you use the new one, surfaces will not be recognized. You'll have to use the old importer in order for the surfaces to be recognized.
