I'm trying to make a constraint allowing the dark smaller cylinder (1) to run in the copper track (2). I want the larger cylinder (3) to be able to rotate around its own axis, while everything is rotating around the Z axis. I've successfully constrained the parts so that all the parts can rotate around the Z-axis but when I constrain the smaller cylinder (1) with the tangent constraint with the track (2) the smaller cylinder is not able to move around on the face, it's just glued to the face. I hope that you have understood my problem, even though my explination might not be the best.

I want the smaller cylinder (1) to recognize the copper faces as solids (so that it can't intersect the surfaces), this would allow the proper movement.  

I've attached an image of the parts. 

Thanks!

Use Transistional - not tangent constraint.

There is a chance Contact Sets might help.

If that doesn't work you will have to go into Environments>Dynamic Simulation.

Attach your assembly here.
