CDS Vignette Plenum Space Question!!

Postby nlally91 » Thu Mar 15, 2018 1:22 pm

I'm testing tomorrow and just want make sure I'm understanding the CDS Vignette. The 4.0 practice vignette has all the same joist size on the 1st and 2nd floor.

But if there are multiple joist sizes and duct sizes, you would find the largest joist and largest duct and add those up for the plenum space correct?

And stemming from that, you think place whatever joist and duct size your cutting through?

NO! Not necessarily. You use the largest combination.
