Example

  1. Consider a <Model> specifying a geometric representation of an airplane, which is to be used for an application in which it is useful to know the position of the bottom of the wheels when the landing gear is fully extended. In this case, the landing gear is represented as a separate <Model>, and the <Geometry Model> of the landing gear specifies a <Contact Point> to identify this location.

  2. The hitch point on a train or pickup truck.

  3. The endpoint of a loading ramp on a roll-on-roll-off ship.
