When you start the Copy/Monitor tool, choose Select Link, and then select Copy, you can copy elements from a linked model to the current project, and monitor changes to the original elements. When an element in the linked model changes, a warning alerts you of the change.
Example: You can copy levels from a linked architectural model to a mechanical model. When a level is moved in the architectural model, a warning alerts mechanical engineers.
Example: You can copy levels and grids from a linked architectural model to a structural model. When a level or grid is moved in the architectural model, a warning alerts structural engineers.
