Use Case shape

In a use case diagram, a use case represents a set of events that occurs when an actor uses a system to complete a process. Normally, a use case is a relatively large process, not an individual step or transaction.

Name a Use Case shape and add other property values

Open the element's UML Properties dialog box by double-clicking the icon that represents the element in the tree view or the shape that represents the element in a diagram.

Tip

Control which property values display on a shape in a diagram by right-clicking the shape, and then clicking Shape Display Options. In the UML Shape Display Options dialog box, select and clear options to display or hide property values.

Hide the name or stereotype of a Use Case shape

Right-click the shape, click Shape Display Options, and then clear Name or Stereotype.

Add extension points to a Use Case shape

1. In a use case diagram, drag a Use Case shape onto the drawing page.

2. Double-click the Use Case shape, and then click the Extension Points category.

3. Click New, type the extension point name you want, and then click OK.

4. Repeat step 3 for each extension point you want to add, and then click OK.

Tip

To hide the extension points compartment of the Use Case shape, right-click the shape, click Shape Display Options, and then clear Extension point. To apply this change only to the selected shape, clear the option Apply to all similar UML shapes on the current page in the Shape Display Options dialog box.
