How to Animate Pneumatic in Inventor

[Flimsor]

I'm trying to check my geometry for our bridge tipper on our cad model, but I can't rotate the arm with the pneumatic not wanting to move. I know you cant change it so that it can move until it hits a limit, but i'm not sure how. Does anyone else know?

EDIT: Whoops, you should enable the "Adaptive" portion in the master assembly along with "Contact Set". You can find both in the browser bar by right clicking the parts or assemblies in question. That should fix what you need to do.
