How to Use the Use Case Diagram Templates in Creately

  • Choose a template that suits your needs

    Pick a UML use case template for your system’s scope. Click “Edit This Template” to open it and define the boundary.

  • Sign in or create a free Creately account

    Sign in or create a free Creately account. You’ll need an account to edit and save your use case diagram; setting one up takes a moment, with no credit card required.

  • Open the template and customize it

    Draw the system boundary, place actors outside it and use cases inside, then connect them and add include/extend relationships.

    • Add actors (users or external systems) around the boundary
    • Place use cases as ovals inside the system box
    • Connect actors to the use cases they trigger
    • Add include and extend relationships
    • Show generalization between actors or use cases
  • UML-correct associations

    The library carries proper UML use case notation—actors, system boundary, include/extend—so your diagram reads correctly to any UML-literate reviewer.

  • Collaborate with your team

    Invite your team to collaborate. Share the use case diagram by email or link so colleagues can co-edit in real time, comment, and track changes together.

  • Save, export, or present

    Save, export, or present. Store the use case diagram in your workspace, download it as PNG, JPEG, SVG or PDF, embed it in a document, or run it full-screen in presentation mode.

FAQs about Use Case Diagram Templates

Are the use case diagram templates free?

They are. You can access and edit the majority of use case diagram templates for free on a basic account, with no download needed. Premium templates and some pro features are available on paid plans if you need them later.

Can I export these templates to Word, PowerPoint or other tools?

Absolutely. Your use case diagram exports as PNG, JPEG, PDF or SVG, so you can insert it into Word or PowerPoint, attach it to documentation, or share it as a standalone file.

What can use case diagrams capture?

Use case templates help define requirements:

  • Functional scope - what the system must do for each actor
  • Actor interactions - users, admins and external systems
  • Include relationships - shared sub-behavior
  • Extend relationships - optional or conditional behavior
  • System boundaries - what’s in vs. out of scope
What do include and extend mean in a use case diagram?

include means one use case always uses the behavior of another (shared steps), while extend adds optional behavior under a condition. Using them correctly keeps requirements clear and avoids duplication.
