If you are on Subscription then you’ll have access to a free download if you own Revit MEP. This download is called the Space Naming Utility which is an intuitive tool that automatically assigns the names and numbers from architectural rooms to Revit MEP spaces. By downloading the Space Naming Utility you can eliminate the need to manually assign names to the spaces, helping save time and simplifying your workflow.

To use, place your spaces in the Revit Model and the utility will then rename/number them properly when executed.
