Moving a few components slide together

Hi,

In https://a360.co/428f4BQ I cannot make the components shaft, piston, and gasket slide all together inside the cylinder.

Appreciate it if you could let me know how!

Right click on the Cylinder Component and Pin in place (or Ground).

problem is that the Joint (Slider 11) acts only on the piston, and the shaft and gaskets stay in place. I created the Rigid Group (Rigid Group 9) but it's not working the way I want to.

If it were my project, I would use Revolute and Cylindrical Joints (better match to real world DoF).

Regardless of the type of the joint, I need a solution that bundles 3 components together. Changing the joint type is not the solution.

It works in the design I downloaded.

I would use the ground-to-parent attribute instead of the pin.

Downloaded you posted model. I functions as you specified you wanted it to. Please clarify your desire.

If you animate Slider 11 joint, you see that only the piston moves. Shaft and gaskets stay in place.

You are using the wrong command to animate your Slider 11 joint. You are using Animate Joint, you should be using Animate Joint Relationships so the your Rigid Group is picked up by the motion.
