Sometimes the built-in Autodesk® Revit® spaces creation gives unwanted results like unnecessary spaces, standard offsets, names, etc.
This simple add-in> reads all the rooms from the chosen linked file and creates spaces based on those rooms.
1) Click the “Create spaces” button.
2) Choose the project which contains rooms to be copied.
3) The spaces are created. The add-in also copies the rooms names, numbers, and offsets.
Works for Revit 2017-2020.
