Activity Toolbox

The Activity Toolbox is used to model system dynamics from a number of viewpoints (represented by activities and the flows between them) in Activity diagrams and Interaction Overview diagrams. Both types of diagram are usually created under Activity elements.

Activities can be stereotyped as a process to display a business process icon; the Activity represents some work that is carried out, which might overlap several Use Cases or form only a part of one Use Case.

Except where discussed here, each element and relationship that you can create using these Toolbox pages is described in the UML Elements and UML Connectors sections of the Help.


The Basic Activity icon adds the Basic Activity Pattern to your diagram as a starting point for developing the diagram (drag the icon onto the diagram to open the Add Pattern <name> to Diagram dialog and click on the OK button).
