Duct worksheets reports net-free size in Revit

[HBDS#20]

When we were working cad our duct worksheets reported out the OD of the metal size for lined duct.
Now working in Revit they display the net free size and not the OD metal size.
I have looked for settings to change this but can't find anything. Is this just how it is with Revit or can we change that to report only metal size?

I don't see anything in the worksheet that would cause this. My best guess is this setting might be checked in the Database settings > Takeoff > CAD Settings > Annotation tab > Size Text group > Always Report Internal Size

Check the lining specification you have set up and see if you have it set to inside dimensions.

Thanks, that was it.
