In a UML Use Case Diagram, each element on the diagram has properties. To see the properties of an element, right-click the element on the diagram or in UML Model Explorer and then click Properties. The properties appear in the Properties window.

Properties of Elements
| Property | Default | Element | Description |
|---|---|---|---|
| Name | A default name | All | Identifies the element. |
| Qualified Name | Package :: Name | All | Identifies the element uniquely. Prefixed with the qualified name of the package that contains it. |
| Work Items | 0 associated | All | The number of work items associated with this element. To associate work items, see Link model elements and work items. |
| Description | (none) | All | You can make general notes about the element here. |
| Color | (default) | All | The color of the shape. Unlike other properties, this is a not a property of the element that the shape displays. |
| Image Path | (none) | Actor | The file path of an image that should be used instead of the default actor icon. The icon should be a resource file within the Visual Studio project. |
| Subjects | (none) | Use Case | The Subsystem or other type that owns the use case. You can set it by placing the use case on a Subsystem in the diagram. |
| Visibility | Public | Use Case, Actor, Subsystem | Public - globally visible. Package - visible within the package. |
| IsAbstract | False | Use Case, Actor, Subsystem | If true, the type cannot be instantiated, and is intended as a base for specialization by other definitions. |
| Is Indirectly Instantiated | True | Subsystem | The subsystem exists only as a design artifact. At run time, only its parts exist. |
| Hyperlink | (none) | Artifact | The URL or file path of the diagram or document to which the artifact provides a link. |
