You can establish relationships between elements in the current project, and monitor changes to the elements.
To do this, start the Copy/Monitor tool, select Use Current Project, and then select Monitor. When an element changes, a warning alerts you of the change.
For example, use this method to monitor 2 grid lines. If a grid line is moved, a warning alerts you so that you can adjust the other grid line, if needed.
You can also use this method when implementing Copy/Monitor in a workshared project.
