Thanks for the reply, for the subfloor it's not the I joist in question.
I don't see the 3/4" subfloor anywhere.
The I joist question was in my other question I submitted; there it isn't putting the correct framing for the roof.
I'm using 16" TJI's for the rafters but the program is only showing 2 X 10 lumper in the framing ortho and materials list.
I'm learning as I go here so I appreciate the help.
