Four fundamental assembly constraints in #nventor allo! comle$ models to be created.

Constraints   The motion of mechanisms is controlled by kinematic constraints and the equations of motion.  2inematic constraints dene ho! arts move relative to each other at joints or contact oints.  0ach kinematic constraint removes secic degrees of freedom from the system.  2inematic constraints can often be inferred from assembly constraints.
