This node contains the attributes for the rigid constraints. These constraints can only be used with rigid bodies. The constraints
            include nail, pin, hinge, spring, and barrier.

                For a constraint between a pair of rigid bodies, this lets you choose where Maya recreates a constraint after you turn it
                  on again. Select one of the following:

                         Recreates the constraint at the original distance and orientation from the first of the two rigid bodies you selected when
                           you created the constraint.

                           you created the constraint.

                         Recreates the constraint at the midpoint between the two rigid bodies.
