Hello all,

Thanks in advance for your help.

Here is the trouble I'm having.  I have created an assembly that is essentially the pedals on a bicycle.  I've used some concentric mates and am able to rotate the pedals within that assembly.  I then have a larger second assembly that I have inserted this first assembly into.  Once the first assembly is inserted into the larger one, the pedals will not rotate.  Any help on this?  I've seen some stuff about sub-assemblies.  Would I be better off using those?

Thanks,

Tyler
