    How can I mate hand-wrist-forearm so hand will also rotate as the wrist rotates?

      Hello everyone.

       

      I'm trying to make a forearm model which I can use for other purpose.

      I need this forearm's hand to do pitch and yaw as well as the wrist/forearm rotation.

      For the parts, so far, I used couple coincident and concentric mates to hold the pieces together.

      The problem was that if I try to mate the hand and wrist(blue part) together by mating planes.. it won't do either pitch or yaw.

      As of now, since those two are not mated, if I rotate the wrist to replicate forearm supination/pronation, hand stays still and won't follow as the wrist rotates.

      What mate can I use for this??

       

      Also, I had trouble making an animation, and I wasn't sure if it was due to very flexible wrist joint so that's why I'm trying to assemble everything again.

      Even though I had an angle limit mate for the device which was assembled on the forearm, when I tried to make the animation, the hand ignored that limit and bent as much as this hand can go. Animation wouldn't show smooth transition...

      I can't show this device here, so it could be hard to understand what's going on.. but does anybody see what the problem is here?

       

      Thanks,
