This is a 1-dim. translational component with two flanges and an additional support. It is used e.g., to build up elementary ideal gear components. The component contains the force balance, i.e., the sum of the forces of the connectors is zero (therefore, components that are based on PartialGear cannot have a mass). The support connector needs to be connected to avoid the unphysical behavior that the support force is required to be zero (= the default value, if the connector is not connected).
Description: = true, if support flange enabled, otherwise implicitly grounded
