If I was using Inventor, I would "Drive Constraint". How to do this under Solid Works - in a simple manner?

Never managed to execute any Motion Study whatsoever, either it will be no-motion-at-all, or - quite often - SWCrash.  Obviously, I don't understand the basic philosophy behind the entire concept?  How to make parts move inside assemblies with minimum effort - besides dragging?  I'd like to do simple things and simple drawings, not fancy animations.  Without any complications or tricks.  How to do that?
