Sheet number, detail number, grid number, and the view name are all Revit properties that are required to be unique — no duplicates allowed. Ideate ReNumber supports the modification of the detail number (viewports), grid number, and view name and has been designed to avoid duplicates during the process of renumbering both the detail number and the grid number properties. This enhancement was made to Ideate ReNumber in May 2017.
Other properties, such as the mark parameter, are allowed to have duplicates, and are not prevented by Revit or ReNumber from being numbered with a duplicate.
