In UML modeling, you can create extension points for
the base use case. These extension points identify where the behavior
of an extension use case can be inserted into the base use case.
To create an extension point:
- In the diagram editor, right-click a use case;
then click .
- Type a name for the extension point and press Enter.
The extension points are listed in the Extension Points
compartment of the use case.
Tip: You can also define
extension points in the Model Explorer view.
