Calypso freezes up in modify CAD model

[Thinh Tran]

Calypso freezes up when I do positioning rotation in modify CAD model tab. If it's a new CAD import with no feature created then it works just fine but if I loaded up the CAD with features then when I tried to rotate the part it freezes. V 7.2.08

Follow up: It just takes a really long time to calculate behind the scene when there are lots of features on the part.
