In the course of playing with my pneumatic assemblies (Usually in front of a Customer) they tend to break !

As an example, the pneumatic cylinder below is a sub assembly with a limit distance mate that provides 1" of stroke.

The orange "gripper" part is free to rotate , but should only rotate between 0 and 90 degrees based on it's mate with

with the cylinder.

99% of the time it works.....

1%...   I seem to be able to drag the part beyond it's limits, which then gets stuck out of position, and even screws up some of the mates in the sub assembly.

The who... is obviously me, but am I missing any best practises that prevent me from "stretching" mates to the point of failure ?

Or, is it just one of those Solidwork things, that the Undo button was built for ?

I realize this is a bit vague, but If you are familiar with what I am on about, I would appreciate any tip that help build a more robust assembly

with something like a pneumatic or hydraulic cylinder.
