Use Case Diagrams.. View constraints on diagram

On different software I’ve developed Use Case diagrams with ‘Extends’ with a constraint which you can easily see on the diagram itself rather than hidden information.

E.g. view appointments might lead to view patient medical records, but only if the end user is a doctor.

Hi klj613,

Thank you for your post. You can add constraint to diagram. I have attached an image showing whated you want to do.
