Hello,
I am looking for moving parts in an assembly done on 3D Experience.
I made a simple remote control ( a box with a button in a cylindrical connection ) and I even made a mechanism representation from it. The mechanical connection looks perfectly fine. 
But when I interact with the controllers with the button, it seems all parts are independant from each other. If I add Rigid body to all elements, the button will fall down like if there were no connection in the first place. 
Thank you for any of your responses,
