Referencing interactions from within other interactions in sequence diagrams

In sequence diagrams, you can reference an interaction from the body of another interaction for the purpose of visual representation. This reference is called an interaction use. You can then reuse the definitions in an interaction to abstract and simplify your application.

You can add and modify interaction uses in sequence diagrams to visually represent interactions in applications.

You can double click an interaction use to open the referenced interaction in another sequence diagram. if you delete an interaction use, the referenced interaction remains intact.

Creating interaction uses in sequence diagrams
In sequence diagrams, you can create an interaction use by specifying a new unspecified occurrence or by creating a new interaction for visual representation only.
Adding and removing covered lifelines to and from interaction uses in sequence diagrams
In sequence diagrams, you can add and remove covered lifelines to interaction uses to visually represent executions in interaction instances.
