Rigid body constraints restrict the motion of rigid bodies. The constraints simulate the behavior of real-world items you’re familiar with: pins, nails, barriers, hinges, and springs.

You can constrain rigid bodies to a position in your scene or to other rigid bodies. If you create a constraint on an object, Maya automatically makes the object a rigid body.

This chapter describes how to work with rigid body constraints. For details on error messages that may occur as you work with rigid body constraints, see Fix rigid body problems.
