Category, hosting and compatibility

The Revit category differs from the catalogue classification. The library lists this family under “Air Terminals”; in a Revit project it behaves as “Windows” for schedules, tags, filters and visibility. This is reported for review. The family was not changed.

How to use a family in Revit

  1. Find and inspect. Open a family here to see its types, parameters, hosting and what was checked. Browsing this website never loads anything into a Revit project.
  2. Request access. Use Request access on the family's page. Our team checks the request and replies within one business day. No file is sent automatically.
  3. With the iBIM Revit plug-in. Open the iBIM tab > iBIM Family > Family Library, choose the family and load it into your model. A family that is already in the model is never overwritten.
  4. Without the plug-in. Load the family file we send you with Revit's own Insert > Load Family.

Families are saved in the Revit version shown on each page. Revit cannot open a family saved in a newer version.
