A UML (Unified Modeling Language) use case diagram is a graphical representation of the interactions between users (actors) and a system to achieve specific goals. The key components of a UML use case diagram include, Actors, Use Cases, Associations, System Boundary, Include Relationship, and Extend Relationship.
Use case diagrams are useful to understand requirements and the functional aspects of a system. They provide a clear knowledge of how users interact with the system what functionalities a system provides and what more is needed to enhance the efficiency of the system.
In this guide, we are going to learn how to create a use case diagram in Visio. So, give it a good read to understand what’s needed to create an efficient use case diagram.

How to Create a Use Case Diagram in Visio?
Microsoft Visio is a tool that supports the creation of various types of diagrams, including use case diagrams. Visio provides predefined shapes and stencils specifically tailored for creating use case diagrams.
Step 1:
Launch Microsoft Visio on your computer. Click New File and then the Software tab.
Step 2:
Under the software category, there could be subcategories, scroll it down and choose the UML use case from the template chooser. It will make Visio provide only the relevant tools that are needed to make use of case diagrams.
Step 3:
Drag and drop the Actor shape from the stencil onto the drawing page for each user or external system interacting with the system.
Step 4:
Use the Connector tool to draw lines connecting actors to the use cases they interact with.
Step 5:
Double-click on each shape to add appropriate labels, providing clarity and understanding. Use the Connector tool to draw include and extend relationships between use cases if necessary.
Step 6:
Customize the diagram by adjusting shapes, colors, fonts, and other formatting options as needed.
Now, save your diagram in Visio format or export it to other formats for sharing or further collaboration. That is it. Your use case diagram through Visio is ready to view. You can keep the source file to make it available for editing again and if you only need the image of the designed diagram, you can export it as well.

Step 1:
Open EdrawMax and select New from the File menu and then click UML Modeling.
Step 2:
Choose Software from the Categories list and select Use Case Diagram from the available templates. All the relevant elements are going to be automatically shown by the tool.
Step 3:
Drag and drop actors from the symbol library onto the drawing canvas to represent the users or external systems interacting with the system. Drag the elements one by one so there is a symmetry while designing the diagram.
Step 4:
Label each actor and use case appropriately to provide clarity and understanding.
Step 5:
Customize the diagram by adjusting colors, fonts, and styles to enhance visual appeal and readability.
