Grounded object not behaving as expected

[Anonymous]

I have an object that has a slider joint assigned to it.  The slider joint works as expected.  But now I want to ground the object, for a short while, so that I can attach another object to using a ball joint.  The second object has each end a sphere  attached.  One sphere  connects to the object that has a slider joint whereas the other sphere  connects to a carriage.  The object with the spheres at each end I called the rod.  So, with a rod connected to the slider I should be able to move it without moving the slider.  But that is not the case.

I am not sure but I assumed that if I grounded the slider object that I would not be able to move it after grounding it even though it had a ball joint on it since it was only going to be a temporary grounding.  But after I ground the slider I can still move it up and down.

Any help or assistance that can be given would be greatly appreciated.

Sincerely,

Joseph

Can you post a bit more info?  Maybe a screencast, or the model, or even just some images would help.

One thing to check:  Do you have a subassembly involved at all?  Are you grounding at the subassembly level?  This can cause some confusion sometimes, because you need to ground at the leaf (part) level for it to be effective.  There's another thread on this that I will look up and reference here.

Thanks,

Here is a recent thread on the "grounding a subassembly" topic:  ground-in-fusion-360-will-not-work.  Not certain that this is your problem, but worth checking out.

That was the solution to my problem.  Thanks ever so much Jeff for the assist.
