Clear inside dimensions for Duct Linings

Clear inside dimensions for Duct Linings

Can there be an option where ducts simply be changed to reflect the true size if a lining is added?

i.e. if I add a 1" lining to my 12x12 duct, it would be nice if the duct increased to 14x14 and I didn't have to change the tag for that duct to free size (i.e. it still shows 12x12).


As far as I'm aware most HVAC consulting engineering companies represent all duct sizes as clear inside dimensions, and so there is not really any point in having two parameters to toggle tags between (one showing "Size" and the other showing "Free Size") which means two sets of tags.


Totally agree. 

This is sorely needed in the consultancy sphere, I believe.
