A plane is fixed on BodyA. The plane goes through AnchorPositionALocal and is defined by the two axes XAxisALocal and YAxisALocal that are also fixed on the first body. The point AnchorPositionBLocal on the second body can only move in this plane.
This constraint removes 1 translational degree of movement (the movement normal to the plane). It does not restrict rotational movement.
