Yeah me too. Out of 3 models that I have imported into my new copy of KeyShot, 2 had missing sections - and I bought KeyShot only to use with Inventor. That's a pretty poor average, anyone in the KeyShot team think of doing any testing? It's not the customer's job to test your product btw. Lofts seem to do it easily (but that's just what I happen to be using right now). Add a few test cases with lofts to your test suite?
