You can indicate that a drawing is not available for editing by locking it. When a drawing is locked, it cannot be accidentally modified. The geometry of the locked drawing still changes when the model changes.

1. In Document manager, select the drawing you want to lock.
2. Ensure that the edit switch is active.
3. Click the Lock column next to the selected drawing.

   You can also select this command from the context menu, or click the Lock button at the top. When you do this, you can lock several drawings at a time.

   The Locked by column in the Document manager shows who has locked the drawing. If you have logged in to your Trimble Identity, your account name is shown. Otherwise your user name is shown.

4. To unlock the drawings, click the Lock column again, or select the locked drawings and click the Unlock button at the top.
