Use case diagram maker FAQs

How do I add shapes to my use case diagram?

There are multiple ways to add shapes to your use case diagram in Miro. Select “Shape” on the toolbar, or press “S” on your keyboard, and grab any shape you’d like. Within the shapes tool, you can also click on “All shapes” to explore Miro’s full list of shapes. Alternatively, you can also drag and drop your own images right onto your Miro board.

Can I export my use case diagrams from Miro or share them with clients or stakeholders?

Yes, easily. Once you’ve created your use case diagram, you can export it in various formats, including image files and PDFs, allowing you to share your work with clients, stakeholders, or team members. You can also generate shareable links or invite external users to view and comment on your Miro board.

Is Miro suitable for both beginners and experienced use case diagram makers?

Yes, we’ve designed Miro to be intuitive and user-friendly, allowing you to drag and drop shapes, connection lines, and even your own images and documents. That means you get to spend less time navigating your tool and more time creating a use case diagram. But if you’re an advanced user looking to build detailed and visually-enhanced diagrams, we’ve got you covered with plenty of customization options too.
