Got an odd issue.

If I draw a duct size over 78" or under 111" that is less than a standard length, I get the error in the attached snip?

112" duct size and larger it does not do it???

It does this on different pressure classes??? some other setting?

Solved- Screwed up stetting

Does someone in-house have CADmep, CAMduct, or ESTmep to try drawing these same items in a non-Revit environment?

They be able to see from those applications what is causing the issue.

Also, what does it say when you click the "Expand" button? Always worth clicking that for your screenshots. Even if what it says is useless, it takes that question out of the picture.
