There are two ways to create a Rotational Scalar using Joint and Body-Body-Point-Direction methods. Connecting properties such as the acting and reacting bodies, and the location and rotational axis on the bodies are defined in the Rotational Scalar creating dialog. When creating the torque, two markers are created simultaneously to represent the torque. The creation steps and parameter definition of the Scalar are same as for Rotational Spring Creation. The creation steps and parameter definition of Body-Body-Point-Direction are same as for Bushing Creation.
