Trouble with multiple joints on one component

[Anonymous]

Hi, so I'm trying to assemble a lamp with articulated arm, the only problem I have is joining one articulation to two different pieces. I'll leave some screenshots of the joints I'm having trouble to attach.

So the bottom part I have already jointed with revolute joints.

And I want to joint the top parts with a single piece, I can joint one with revolute, but when I try and joint the other, they don't seem to "move to joint".

As I mentioned in the Screencast, you are creating a lot of sub-assemblies with just one component.  If you are planning to add other components to each of these sub-assemblies great but I would bet you are not so please stop this practice.

Now, in the Screencast, I first of all suppressed the Motion Link, it serves no purpose in your assembly at this point.  Second, I grounded the base so you have something to move the other components against.  Again this is harder to do than normal because you have to find the component below one of your many sub-assemblies.  Then I deleted the problem, yellow in timeline, Rotate joint and replaced it with a Cylindrical joint.  In a four link system, like you have, your are probably going to get some little error on the plane the other Revolve joints are created and a Cylindrical joint will revolve and give you a little planer movement, if needed.

Thank you so much, it wasn't impossible after all. Life saver.
