• Cylindrical4[cnum, axis1, axis2] constrains axis1 and axis2 to be parallel and coincident.
• Cylindrical4 constrains four degrees of freedom.
• Cylindrical4 models a hinge or revolving bearing that can translate along its axis of rotation.
• The first two equations constrain the origin of axis2 to lie on axis1, and the second two equations constrain the two axes to be parallel.
