A SixMotion object defines the relative 3 translational and 3 rotational motion DOFs at one body with respect to another body. To create a SixMotion object, five dummy bodies are created in the same location and they are connected with 3 revolute joints and 3 translational joints. SixMotion is not supported via a creation button, but can be created by selection of for the connector type in the joint properties dialogs.
