Lock

If you open a document for editing, the drawing management will require the locking of the drawing. This isn't to be confused with the locking of the file system on the document, what happens additionally.

If a drawing is opened only for view, it can be opened as a copy as well.

If a drawing is locked, you cannot edit the details or delete the drawing.

 

Unlock

If you close a locked document, which was opened for editing, a request for unlocking occurs. In case of unlocking you can enter a comment about the change content, which will be recorded in the protocol.

If the user decides against unlocking, the drawing will stay locked until this user or a super user unlocks it.
