Create custom deck framing

[Bill B]

I want to create a 24X24 deck. It has a 6X6 posts at each corner. Each post is set in concrete - 18"w X 32" deep. Two 11 7/8 X 1 3/4 LVLs nailed together are placed on top of each post to form the square. The double LVL against the house is bolted to the 2nd floor framing. Then I-Joist construction (11 7/8 X 1 3/4 PT) spaced on 16" centers provides the remainder of the framing.
I have read all of the deck framing articles and have gone through the framing tutorial(s) several times.

Using the build deck tool, I can create the basic deck. But when I modify the automatic post structure, I cannot see them in plan view (yes, all of the framing options are turned on).
When I modified the joists to 11 7/8 they poked up above the deck level when in 3D perspective view and I cannot figure out how to modify all of them with defaults.
Basically, I'm frustrated in trying to create this beast.
Any suggestions will be most welcome. Thanks, Bill.
