Vignette duct space required question

[bmccall14]

If the largest duct on the floor runs parallel to the joists, do you still account for its height? Or do you just allow space for the largest duct that runs perpendicular to the joists because technically the largest parallel could run between the joists?

Read the program again.

I believe Dorfs video says that you are supposed to leave enough space for the largest duct + the largest joist.

That's incorrect. It's the largest joist/duct combination.
