Lock Diagram

You can lock a diagram against inadvertent changes, such as moving or sizing elements.

To lock a diagram, follow the steps below:

  1. Open the diagram to lock.
  2. Right-click on the background to open the diagram context menu.
  3. Click on the Lock Diagram option to prevent further changes.
  4. Click on the OK button.

If a user selects an item on a locked diagram, the object border or outline displays in red.


This does not apply in the Corporate, Business and Software Engineering, Systems Engineering and Ultimate editions if security is enabled. In that case, see the Lock Model Elements topic.
