moving bodies in a component

[giovanni cantanaro]

Good morning.
I have a hinge formed by three bodies, the two attacks plus the pin. how do I move an attack based on the pin.
Thank you.

fixed bonds an attack, from the various concentric couplings between the pin and the attacks (without blocking concentricity) and then impose a free angle coupling giving it the values you need (0-180 for example).

I'll give you an example of a zipper I've got, it's missing the pin but it's things that I take away to lighten the overalls, but the constraints are those.
a fixed part and the others run behind them
