I've done assemblies before but never had this problem.
I make a concentric mate with two parts and then they don't rotate around the axe and I can only move them to the sides.
It's possible I clicked something by accident but I don't know how to fix it, and I can't find an answer online.
From searching the web it seems like I set a mate the prevents the part from rotating but I only have one mate!
It also doesn't rotate if I mate the axes.
Please help...! It's driving me crazy..
