When i mate the hinge to the leg and the bottom of the table i am using extruded circular cuts with concentric mates that. One goes through the hinge and into the bottom of the table and the other goes through the other side of the hinge and through the leg. The only other mate that i am making is along the bottom of the table and the flat back side of the hinge. It tells me i a fully defined so that movement is restricted. How to i make the hinge actually work like a hinge in the full assembly?
