Motion control in SimMechanics 2nd generation!!

Hi,

I am using a revolute joint between two bodies. Is it possible to control the revolution, like say it should rotate only 60 deg. How can i control the joint motion in 2nd Generation. I tried using position targets, it doesn#t seem to work.

Or should is it easy in SimMechanics 1st generation??

Thanks a lot!!

Best, Vish.
