Opening diagrams
If you open a diagram in ARIS Architect/ARIS Designer, it is locked for write access by other users when opened, or a message is displayed stating that it can only be opened in read-only mode if another user has already opened the diagram.
To prevent a diagram being automatically locked for changes by other users when you only want to view it, in ARIS UML Designer diagrams are always opened in read-only mode. The corresponding lock is only requested from the server and the diagram is updated when you attempt to change the diagram, so that you are editing the diagram in its current state. If it is already being edited by another user, you will see a corresponding message.
When saving, in ARIS UML Designer all locks are canceled.
