Diagram content
The UML specification states that product manufacturers can extend the typical content it proposes for the different diagram types with content of other UML diagram types.
ARIS UML Designer supports any UML content for structure diagrams. In addition to the elements provided for the corresponding diagram type, you have the option of modeling all other UML constructs. This enables overview diagrams to be created, for example containing both class hierarchies and complete state machines and interactions in Sequence diagram notation. This also enables UML elements that are actually assigned to different diagram types to be linked to one another graphically.
Figure 25 shows elements from Class, Use case, Component and Activity diagrams together in a single Class diagram.
