Locking and Unlocking Objects in the Workspace
You can lock an object to avoid unintentional modifications. When you lock an object in the Workspace, its status becomes read-only, and the object cannot be overwritten until it is unlocked. Locking is a Workspace feature and is not available in Commonspace.
The Lock command is available in the Windchill Workgroup Manager client user interface. To lock an object, select the object and click File > Lock. The object becomes read-only, and is marked as such by a status icon in the General status column. To unlock a locked object, click File > Unlock. The Check Out command automatically removes the lock from an object.
* 
You can set the Automatically lock objects added to workspace preference to Yes to lock all objects, by default, as they are added to the Workspace.
* 
The CAD worker ignores the Automatically lock objects added to workspace preference and successfully publishes the CAD documents, which are locked.
When you lock an object which is modified in session, the object does not become read-only. You must lock an object before modifying the object in session.
When a file is locked in the Workspace and then opened in a CAD session, the menus related to editing the objects become unavailable. For such objects, the Save command opens the Save As window, enabling you to save the object with a different name.
