The Class Model describes the various domains in the system and the Classes and instances within them. It sets the underlining foundation upon which objects will be put to work, providing a flexible foundation upon which systems can be assembled in component like fashion. Development of the object architecture starts with an identification of domains and an initial set of object classes using a Class Diagram.
You can view the Class Model part of a model through the Class Model folder in the Relationships pane.
