TL;DR - 15 floors... 300,472 sq.ft. living space... 2,018,386 lbs. lifting capacity...
Mocked up the interior of the ship. Added 15 floors that are 15' high. This should provide enough room for raised floors & drop ceilings to run electrical, hvac, plumbing, etc.
Level 12/13 is combined into a 30' high bay for ballroom dancing, zero-g basketball, or whatever you like. Levels 14 & 15 are the decks at the top of the ship. At the rear is maintenance, engineering (engine room), and housekeeping. Lots of space back there for life support, HVAC mechanicals, & water/sewage storage. Level 11 wraps around to the wings for more cabins, viewing areas, bar, restaurant, etc. It's a long corridor about 20-25 feet wide.
Total living space is 300,472 sq.ft. (including atrium, engineering, etc.).

Subtracting these areas & cargo hold from the main body cavity leaves a lift envelope of 29,682,149 cu.ft. At 68lbs of lift per 1000 cu.ft., it can lift 2,018,386lbs. Or 1009 tons. The "pink balloons" are estimated/visual. They are 1000cu.ft. each (10'x10'x10'). Couldn't manually model and neatly pack 29,682 mylar balloons (that's the engineer's job). Here is the shape of the lifting envelope. Note the channels removed for Level 11 in front of the wings. "Ten Forward", or technically "11 Left" & "11 Right"

Of course this abandons the idea of retractable wings, unless you want to sacrifice lifting capacity. I vote for non-retractable wings. The loading platform is also unnecessary with a detachable cargo bay (and would lose more lift capacity). Also thinking about redesigning the archway area when I get around to making the cargo bay detachable. Looking to modify for more space to the lower levels, and allow a level to reach the cargo bay from inside the ship.
Here's a picture from space inside Level 15.

Here is a screenshot with measurements for an 8 foot high skull (it's about 5 feet wide). It's a mirror image so use the same measurements on the other side.

Don't know a good way to figure out the angles. If you attempt to build it, you'll probably have to play with the connections before tightening them down. Most of the orange faces are "almost" flat, but not perfect.
The only part that is perfectly flat is the rim around the base. Perhaps start there and build up.

I was reading the same page a few days ago!
Found the same 68lbs/1000cu.ft. That means 1300 tons for the 39 million cu.ft. volume. Did you read the comments about recompressing helium instead of venting it? http://www.airships.net/helium-hydrogen-airships/#comment-589500
I will email Donna today.

I have a request. We need to know the air displacement of the shell. This volume will determine how much it will lift. We'll need to measure the helium/hydrogen air bag volume needed to lift the craft without thrust if possible. The airfoil still needs to be maintained so that capacity is increased with forward thrust/lift.
Hi Ernie. I'm still listening to yesterday's archive. I'm glad you like it.
For cubic volume, I used the main "body" (without the movable wings, engines, "skull", or the tail).
[attachment=0]p13.jpg[/attachment]
At its current size, it calculates to 39,309,656 cu.ft. If you chop off the wings (fuselage only), it drops to 23,256,222 cu.ft.
Do airfoil's work at that scale? The wings are over 600' long. I'm not an engineer, but imagine you'd need extreme air flow to get lift from something that large.
I'm sure I'll be too nervous to be useful on the show. I'm very quiet (100% introvert). I'm the complete opposite of you on your show. But if you like, we can try an aftershow, or something where I don't have to worry about sounding horrible.
Thanks.

Thanks. I'm sure there will be a 3D printable version in the future. I'll need help figuring out how to prep it for a specific printer/technology, and if it should be all one piece, or something you put together (separate engine pieces, solar panels, etc.).
Made a rendering of the wings collapsed for "hypersonic mode" (and fixed an issue with the solar panels).

Added windows & more solar panels...

Have been working on this since Ernie asked Larken to build a 3D model in Blender. I've finally gotten it to a point where it looks like something. Haven't done much of the detailing. The guns are pretty basic and I couldn't figure out how to integrate the windows into the 3D mesh. Detailing can go on forever, so I figure I'd better get some feedback on what I did right or wrong before trying to do more.
It's huge! I tried modeling to scale based on the drawing and its 1033' long, 1093' wide, and 386' high (231' to top of the deck). I think I remember hearing "100 feet tall". It this a cargo ship, or a starship?
I haven't applied any materials to the surfaces (other than to show glass vs. metal). What style should the ship follow?
1. Enterprise D - A clean, shiny, pride of the federation (state) with no defects (pretty much what it looks like now).
2. Nebuchannezzar / Millenium Falcon - A (dirty) rebel ship. Held together by it's "loving crew".
3. Serenity - Ridden hard, put away wet. Minimal maintenance. Nearly falling apart.
4. Reaver Ship - Falling apart. Held together with human entrails & items of conquest.
Of course the more detail, the longer it will take to finish.
I'm not sure what to do with the tail (it needs a lot of work). Can someone sketch up a detail of the stern? Is it a wall of thrusters like a Star Destroyer? Or a giant door like a C-130? Or bunch of docking bays for shuttles to land?
Also not sure how the sail works. Made it a grid of solar panels that collapse into the proper shape. Included a pic of them expanded, but I don't think it's practical to capture sunlight on a curved surface. Was thinking something that opened like a Chinese fan could pivot toward the sun (in any direction). Maybe origami solar panels?
Please give some feedback. I mostly used the detail sketch to build from (thanks for making it). But once it was taking shape it looked a little different than Scott's final rendering. The wings look a little "fat", but could be useful if the ship is mainly for transporting cargo.
Attached some pictures... (can only attach 3 per post?)
