Bottom of Duct is Reporting Bottom of Insulation

[MaxChilds]

When I schedule a section of duct that is ready for fab, it reports the bottom of the insulation instead of the bottom of the duct. If I just tag the duct with elevation it comes out right. If I take the insulation off, then it reports right but I need the insulation for the hangers. Is there a way to change this in Revit?

Thanks,
Max

Add a calculated value parameter = Bottom of Insulation - Insulation Thickness?

Hello @MaxChilds ,

You could use a TAG that shows the Bottom of the Duct like I did in the picture below or use the Spot Elevation.

Is that what you want?

just open the TAG family "M_Top Elevation Duct Tag.rfa" from the library an change the Label parameter to Bottom Elevation.

ToanDN, 

That is what I was looking for.

Thanks.
