Class relationship direction

Is it possible to show the direction for class relationships in class diagrams. There should be a triangular arrow that points in the direction that the class relationship phrase referrs. I’m calling the name of the connector between two classes the “class relationship phrase.” This is different than “Navigatable”

Dear ianxm,

Thank you for your message and sorry for my late response. You can show the direction of the relationship by right click on the association and select Show Direction. If you have any further questions, please feel free to contact us again.

Best regards,

excuse me …but I have read that “show direction” is a label direction indicator …Is this equal to a uni-directional relationship?

How can I represent a uni-directional relationship in VP-UML?


Hello mileruiz,

To represent a uni-directional relationship, you have to set one side to be non-navigable and the other side to be navigable. You can set the navigability in the specification dialog box (Right-click on the association and select Open Specification from the popup menu)

Best regards,
