For MEP Revit users who rely on space elements, the Space Naming Utility has been a great addition to the Revit workflow. It speeds up a usually manual process of copying architectural Room names and numbers to corresponding spaces.
For years it was available to download and install and very easy to track down in the Add-Ins tab. Autodesk decided to integrate it into Revit with Revit 2017.1, which is great because you don’t have to download it separately anymore. However they moved it, so if you go looking for it in it’s old home you might get a little confused.
Very easy to resolve, go track it down under the Analyze tab and you are all set!
