The <Model Library> and <Model> Classes
A <Model> specifies its own spatial frame of reference, which is usually LSR - a 'Cartesian' reference frame.
A <Model> object may specify a <Feature Model>, a <Geometry Model>, or both.
The following examples will discuss <Model> solely in terms of <Geometry Model>, because the model instancing mechanism for <Feature Model> is the same.
