Is it possible to have element specific project units?

[tbrown6608]

I am using Revit MEP 2012 and I created tags for air terminals that read the size of the air terminal and also controls the physical appearance of the air terminal. Basically if I change the tag to read 12"x12" the air terminal changes to this size. In order for it to appear correctly I had to change the project units to inches. Now I am creating a tag for mechanical equipment to work the same way but I want the tag to read in feet not inches. This obviously conflicts but I am wondering if there is any way (I doubt there is just trying my luck) to set the default units to a specific element so this is possible?

If not I'll just accept the mechanical equipment tag to read in inches but if anyone has any ideas please let me know!

I don't think you have have different units like that. This is how I accomplished a similar situation:

Project Units: Feet,  I want a length to read in Inches

The Parameter "Length" controls the constraints of the family as typical. A Shared Parameter is placed family as an Integer type. The formula for this parameter is =Length / 0' 1". The Tag's label references this Shared Parameter and adds the suffix for the inches symbol.

Thank you. This does works.
