When Should I Use Copy/Monitor?

Use the Copy/Monitor tool when

The architectural team, the structural team, and the engineering team use Revit software.
Each team must be informed of changes to levels, grids, and other elements.
The teams will link project files to work on the same building design. Each team maintains its own edition of the project file and uses Revit software to develop the design for their discipline. Each project file is linked to the other project files to share information about changes to monitored elements in the building design. (For an alternative method, see Copy/Monitor and Workshared Projects.)

Example: The architect uses Revit Architecture to design the architectural model. The structural engineer uses Revit Structure to create an empty structural project. Then the structural engineer uses Copy/Monitor to copy levels and grids from the linked architectural model, providing a starting point for the structural design. Likewise, the architect links the structural model into the architectural project to monitor levels and grids. Whenever the architect or structural engineer moves or changes a level or grid, the other team member is notified of the change.

Example: The architect uses Revit Architecture to design the architectural model. The mechanical engineer uses Revit MEP to create an empty mechanical project. Then the mechanical engineer uses Copy/Monitor to copy levels from the linked architectural model, providing a starting point for the mechanical design. Whenever the architect moves or changes a level, the mechanical engineer is notified of the change.
