mate ball and limits

hello,
i am trying to imitate a person and his movements,
therefore i found a manikin where i can connect de different parts with ball mates, but my problem is that with this type of connection i cant fix limits for the movements.
is there any possibility to do it? i wanted to do like some revolute mate combined but restricted so i can restrict to "normal" movements of the human body. for example where the red and black movements are in the plane ZX and the green movement in the YZ plane

Ok, ball mates do not support limits. That said, you can do this very easily by using two revolutes (that do support limits).
One revolute per degree of freedom of the (human) joint.
Two mates, one for rotation about each of two planes, each with limits.
