Connecting properties such as the base and action bodies, and the location and translational and rotational direction on the bodies are defined in the Screw Joint creation dialog. When creating the joint, two markers are simultaneously created to represent the joint. The z-axes of the markers are defined as the translational and rotational directions. The other axes of the markers are determined by the right hand rule. The creation dialog and parameters are the same as for Revolute Joint Creation with the option of Body-Body-Point-Direction creation.
