After creating mass floors, you can tag them in 2D views. The tags can include information about the area, exterior surface area, perimeter, volume, and usage for each mass floor. If you change the shape of the mass, the tags update to reflect the changes. (For information about tags, see Tags.)
Revit provides the Mass Floor Tag and M_Mass Floor Tag families. These tags provide information about the usage and square units per mass floor. They reside in the following folder:
%ALLUSERSPROFILE%\Autodesk\<product name and release>\Libraries\<locale and language>\Annotations
To display other parameter values in a mass floor tag, create a tag family that include the desired information, as shown.
Sample tags for mass floors
To tag mass floors
You can tag elements in 2D views, including plans, sections, and elevations. You cannot tag elements in 3D views.
See Applying a Tag by Category and Tag All Not Tagged.
When you enter usage values in tags, other areas of the project (such as element properties and mass floor schedules) update with the information.
