Quote - Check the file menu at (and since I don't have it open, atm - I'm guessing. I think it's under figure) Figure/Limits or Set Limits. If that's checked, there will be certain things that you can't do with a joint like a bend or a twist that can't be done to the real joint :). If you still want to twist the hand anyway, uncheck the Limits.

Some limits may be "forced" by a setting in the CR2.
To change that you have to edit the file.
