Lock Model Elements
When security is enabled, you must have Lock Objects permission to lock an element.
You can lock:
- A package, element or diagram using the corresponding Lock context menu option in the Project Browser, and
- An element or diagram using the corresponding Lock context menu option in the diagram.
Under the standard security policy (Require User Lock to Edit deselected), when you select the Lock option the Element Lock dialog displays:
The four lock options available are:
- No lock - do not lock this element; clear any existing lock
- Full lock - lock this element so that no-one can edit it
- User lock - lock this element so that only the locking user can make further edits
- Group lock - lock this element so that any member of the specified group (in the GroupID field) can update the element, but others are excluded.
Select the appropriate lock and click on the OK button.
If the item is already locked, only the appropriate lock option and No lock are available. You have to release the lock in order to set a different type of lock.
Under the rigorous security policy, a different dialog displays. See the Apply a User Lock topic.
If a diagram is locked and you select an object on it, the object border displays in red. This indicates that you cannot change the object.
