To resize the system boundary, select the shape, and then drag a selection handle.ĭrag Use Case shapes from the Use Case stencil and place them inside the system boundary, and then drag Actor shapes to the outside of the system boundary. Click outside the shape on the drawing page. To indicate a System Boundary in a use case diagramĭrag a System Boundary shape onto the drawing page.ĭouble-click the System Boundary shape, and then type a new name for the system or press the DELETE key to delete the existing name. Note: If the tree view is not visible, on the UML tab, in the Show/Hide group, select Model Explorer.
Then select either Metric Units or US Units. In the dialog box, select the blank template. To rename a drawing, double-click to select the default name (such as Drawing1) at the top of the drawing and then type a new name over it. The new diagram, with the related stencil, opens in your browser.ĭrag Use Case shapes from the Use Case stencil and place them inside the subsystem boundaryĭrag Actor shapes to the outside of the subsystem boundary. When you find the diagram you want to use, click its Create button. The other items in the row are sample diagrams that have some shapes already drawn to help you get started quickly. The first item in the row represents a blank template plus the companion stencil. In the Gallery, scroll down to the UML Use Case row. Near the upper right corner of the page, select More templates. For more details, see Self-service purchase FAQ. If your admin has turned on "self-service purchasing," you can buy a license for Visio yourself. For more information, contact your Microsoft 365 admin. Note: Creating and editing UML diagrams on Visio for the web requires a Visio Plan 1 or Visio Plan 2 license, which is purchased separately from Microsoft 365. Glue the other endpoint to a connection point on a Use Case shape.įor more information about use case diagrams (and procedures for using Microsoft Visual Studio to create use case diagrams), go to UML Use Case Diagrams: Guidelines. Glue one endpoint of the Association shape to a connection point on an Actor shape. In a use case diagram, drag an Association connector shape onto the drawing page.
Shows that one use case adds functionality to another.Įxample: To indicate a relationship between an actor and a use case Shows how a use case is broken into smaller steps. Indicates that a use case is a specific way to achieve goals of the general use case. Indicates that one use case has a dependency on another.
Shows the relationship of an actor to a use case. Use connector shapes to indicate relationships between shapes in the diagram. To resize the subsystem, select the shape, and then drag a selection handle.ĭrag Use Case shapes from the UML Use Case stencil and place them inside the subsystem boundary, and then drag Actor shapes to the outside of the subsystem boundary. The subsystem can represent your entire system or a major component.ĭouble-click the Subsystem shape, and then type a new name for the for it, or press the Delete key to delete the existing name.

(If you don’t see the Shapes window, go to View > Task Panes and make sure that Shapes is selected. A UML Use Case stencil is open in the Shapes window. You should see the Shapes window next to the diagram. (A description of each one is shown on the right when you select it.) Then select either Metric Units or US Units. In the dialog box, select the blank template or one of the three starter diagrams. From the search results, select UML Use Case.
