The 
Line on Plane Joint locates an axis to a plane, controlling two DoF's (one translation and one rotation). The object line in this assembly can slide in any direction on the target plane and can rotate about two directions while maintaining contact with that plane. Some example applications of this joint include a pin in a deep slot and a cylinderical roller on a surface.
