Restore redline 

Selected closed redline objects can be restored to an open status. A redline object may need to be restored when a revision has not been performed satisfactorily.

To change the state of a closed redline back to open:

Select the redline.

Select the command.

The selected redlines are returned to an open status and the redline color changes back to red. The original redline creation date is displayed. Redlines can also be restored by selecting one or more redline objects and deselecting Picked Up from the Object Info palette.
