About Pins

A pin connection models a cylindrical pin inside the cylindrical face of a rotating outer part. The outer cylindrical faces rotate against the pin but cannot move axially with respect to each other.

Defining Pins

Examples of pins in assemblies include the hinged joint in laptop computers, pliers, and actuators.

The pin connection applies an underlying hinge restraint in which the outer part is allowed to rotate freely about the cylindrical axis while the other five degrees of freedom are fixed.
