Hi! Using Revit 2020 and I'm modeling some return air ducts with return grilles that are located directly on the duct. I downloaded the families from Titus HVAC ( here is the link to the family https://www.titus-hvac.com/Products/Grilles/S8F ) and for some reason, I cant add them to my Return Air duct system. There is a video below- A regular air terminal included in the mechanical template shows "layout" and "create systems" options in the ribbon, but this one I've downloaded doesn't have those options, even when I disconnect it from the duct. When I check using the tab key I can see that the grilles aren't part of the system. I've been stumped all day. How can I connect these grilles to my return air system?
