After you establish relationships between elements using the Copy/Monitor tool, you can perform a coordination review to view and address any warnings generated by changes to those elements.
The Coordination Review dialog displays a list of warnings for monitored elements. If you are reviewing warnings for a linked model, the Coordination Review dialog displays warnings for the current (host) model and the linked model on separate tabs.
Revit highlights the element in the drawing area. If needed, Revit opens another view to display the element.
If you want to see the changed element in a different view, you can double-click a view name in the Project Browser without exiting the Coordination Review dialog.
Accept difference : Acknowledge the difference between the local model and the linked model. Make no changes to the local model.
Use comments to communicate with cross-functional team members. When other team members open or reload the linked model and perform a coordination review, they can see these comments for each changed element.
