How to allow a joint to move in space

Jibe1982

Hello, I am very new in Sketchyphysics.

So here is my question:

I would like to bind to bars together by a hinge, but as I do this, I cannot allow thoses two bars to move in space, I they can rotale along the hinge, but the hinge itself cannot move in space. I'm sure it's not so hard to do, but at my level, I have no clue how to do that.

Could somebody please help me. Hope that my explanation was clear enough.

Thank you in advance, JB

It would probably be better if you make an example model and post it, otherwise it's hard to grasp or even explain.

But here are some pointers:

if you want movable joints add them to a movable group(create a box, then create a hinge, now group them together)
if you want those joints stuck to a static object simply create a new box, make it static, then connect the movable joint to the static box
