Is there a way to set parts in an assembly so that they will simulate contact while you try to move one of them?    In Inventor, I would just take the parts and create a contact set. 

I'm not sure how to do the same thing in Solidworks.   Define contact set is greyed out. 

I'm poking around in motion study, but that doesn't seem to be what I want.

Scenario is that I want to check if a part can be installed / removed from it's location, given the other solid parts around it.
