You could use theRigid Body Joint constraint

that’s exactly what it is supposed to be like, only thing is, i can’t really find out how to make the joints and all that. could you maybe make a fast tutorial, briefly showing how you did it???

A quick demo on the principles used for each of the swinging objects.

That went perfect, thanks for the demo :slight_smile:
