Hi Andrey,

Did you try deleting the relation by pressing [Delete] Key?
Please try [Ctrl]+D.

[Delete] removes the element of selected model from the Diagram and the model will still stay in the Project file.

[Ctrl]+D, on the other hand, deletes selected model from the Diagram completely.
or you can delete model from its pop-up Menu (Right-clicking)






















or you could use Main Menu. (Select model then [Edit] - [Delete from Model])































Best regards,

Hi,

In Class diagram editor when I delete association, generalization or dependency relation this changes don't reflect to actual state of objects relations.

So, I have to delete this relations manually and only after this I can add new one.

Thank You!

Regards,
Andrey
