I am trying to figure out how to simulate living hinges and compliant mechanisms, but I am unable to achieve any desired results, and so the only way of testing my parts is to wait a few hours for the parts to 3d print (which ain't ideal).

Heres the example of the option which is missing in my Solidworks, compared to a tutorial on Youtube and the part which I am trying to simulate;

No rotation option?! - Album on Imgur 

If anyone is able to shed some light on the missing option or even suggest a way of simulating the bending of the hinge it would be super appreciated.

Cheers
