Locking and Unlocking an RBD
You can lock any diagram in the RBD Table, regardless as to whether it is a block diagram or a phase diagram. Locking a diagram prevents its layout from being changed. In a locked diagram, you cannot insert, delete, or move diagram objects. However, you can still make changes to both diagram and object properties.
To lock the diagram, do one of the following in the RBD Table:
Right-click the diagram and select Lock Diagram.
Select the diagram and then select RBD > Lock Diagram.
In the RBD Table, a lock icon is shown next to the diagram’s identifier to show that the diagram is locked.

When a locked diagram is active, the Lock Diagram command is replaced by the Unlock Diagram command, which you can then select to unlock the diagram. A Lock icon follows the identifier of a locked diagram.
