I want to introduce slackness in all the revolute joint , that is due to clearance joint need to introduce some play in the joint.

Rajesh,

I've had some luck using a planar joint with hard stops constraining the translational degrees of freedom. I'm modeling a four-bar linkage and i'm able to model the oversized holes in one link (two revolute joints), but when I replace the third revolute joint with a planar joint the model does not assemble correctly. I think this is a very basic capability that Multi-body should have since in the real world joints are not perfect.
