    Tags are text labels that display information from a model element. The tag in the illustration above is a Multi-Category tag showing the Type Name and the Type Mark for a length of Flexi-Duct in Revit MEP.

    Multi-Category Tag Location

    Ribbon > Annotate Tab > Tag Panel


    Multi-Category Tag – Function

    Attaches tags to elements of multiple categories, based on a shared parameter. To use this tool you must first create a multi-category tag and load it into the project. The element categories to be tagged must include the shared parameter that is used by the multi-category tag.

    Create a Multi-Category Tag

    Click the File Button in Revit 2019 (in older versions click the big R on the top left of the User Interface). Click New Family and in the New Family: Select Template File, open the Annotations folder and select the Metric Multi-Category Tag as illustrated below.

    The label should look like this:


    Now save the new multi-category label/tag and then load it into your project. You can now tag model elements in your project.


    Double click on each new tag in turn and insert the Type Mark value.


    MEP Components tagged with Type Name and Type Mark



    Most new Revit users will make a unique Tag for Doors, Windows, Floors etc, that will all tag a single parameter such as Type Mark. This is fine if each of these Tags need to graphically look different i.e. Font, Size, Linework. But, what if all these Tags which tag the Type Mark all look the same? Instead, try creating a single Multi-Category Tag. This will greatly reduce your Tag family quantities in your content library. Your content library could now contain a separate Multi-Category Tag for commonly tagged parameters such as:

    • Description
    • Manufacturer
    • Mark
    • Model
    • Type Mark
