My whole assembly is grounded. How do you select just the base or a group of parts t?

Hi All,

I am new to this forum and to Pro Mechanism. I have an assembly that was created in standard mode and the entire assembly is grounded. I need to operate two air cylinders with a slider connection and I want them to push a coupling and a shuttle nest. How can I group the nest the jam nuts and the coupling all to move when I move the piston in the cylinders?

Happy New Year
and Thanks in advance
Dan Yoder
