Two parts each with a hole. I want each piece to revolve around a pin.

I am a teacher. We, my student and I, have two parts each with a hole.  I want each piece to revolve around a pin.(sort of like a free wheel on a toy train) I can put the pin into one hole using resolute but as soon as I try to use the same pin to fasten in any way to the other hole I get errors. I am really frustrated now - I have been struggling for days and am losing my student's interest.

    thanks for reaching out.  You should be able to use the command 'fix' on the pin and then use a revolute mate for each of the 'wheels'  Make sure you are only 'fix' the pin or it is overconstrained

    here is a video demo.  This is before round wheels were invented.

    Note the 'axle' is inserted and do not move before hitting green check. That puts it in the original design location.  Then first thing is right click 'fix' the axle which locks it in place.  Add two revolute mates for only rotation freedom on the square 'wheels'
