Linear Slot diffuser - Return

[sameerkhankhattak]

Can anyone give me CEILING return linear slot diffuser having rectangular. I don't have much experience on families so cant make one myself and don't find the CEILING linear slot diffuser in libraries. Thanks

If your using linked models, better to use face hosted families rather than ceiling hosted because the ceiling in the linked model won’t be recognised when trying to place the family.

Face hosted families can also attach to any surface, vertical (wall) or horizontal (ceiling).

Also, since you highlighted that you want return diffuser, if you find a supply diffuser just open the family, select the duct connector, change the classification to “return” and change direction to “out”, save and job done.

Learning to create and edit families will be an essential skill. In most cases manufacturer, or the internet give you only something that is approximately what yo want, never exactly what you want. 

you can use a SUPPLY diffuser and change the duct connector to "RETURN" or exhaust.
