Joint moving the wrong Part

In my revolute joint, I want a certain part to move, and the other to stay stationary. The one I want to stay stationary is moving, and the one I want to move is stationary. Any help? (I'm new to Fusion, by the way).

 

Thanks,

Oliver

Hi,

Stationary component > rightclick > ground

the only way to force a component to be stationary is to ground it, or rigid joint it to something that itself does not move.  Fusion joints to not have any sense of "this component moves and this one does not".  The preview in the command seems to imply this, but that is, IMO, misleading, because in a general solve, either component is free to move.

Just have this same problem.
I'm able to make a rigid group from sub assembly's parts, but then it's manually added midplane (between 2 sides of one component) does not move along.

Cannot just ground the induvidual parts in sub assembly because then they are unselectable while doing joint.

 

what gives?

like he says

grounded is unselectable, but only as first selection!

First selection is going to move to second selection.
So first must select the floating component.

 

It was just a matter of cliking in the right order!

I'm picturing a cylinder that is pinned or otherwise grounded. There is a shaft inside that cylinder that you want to rotate as the cylinder remains still. Right click the joint and see Animate Joint vs Animate Joint Relationships. Animate Joint rotates the housing (not your desire), Animate Joint Relationships rotates the shaft. This drove me crazy for a while. I feel your pain.
