Interesting Shape -How would you go about this shape?

have you got a reference image for the backside?
Unfortunately, I don't.
But I find its the continuous sweeping line from the opening in the dome that goes out along the edge of the balcony (if you can call it that) which is the most interesting feature. It is curious how the architect pictured the back joining given that the dome and base meet along the left edge.
Glad to see I caught at least one persons imagination.

I thought the basic shape was a flattened sphere cut by two smaller flattened spheres, then the center part is cut and curled back. As I look at the enclosure at the center in the picture, I can't figure out what's happening at the other side. It looks Escheresque.

ahaha true

I know its tricky, Lots of ways to go about it but none that quite respect the image.
pbacot, nice organic approach, SS?
I went with a more brute force approach. Its close but still not quite there.
Quite a tricky little designee

mmm.. the big glass surface should be curved on xy too.. you did it straight..

pjbazel,
That's a house sketch by Jacque Fresco, from Venus, Florida. He's a futurist-style architect, with grand civilization concepts (sort of like Bucky Fuller was.)
I played around with the design, to create in SketchUp, something akin to this house sketch.
I started with a sphere, and stretched it, with multiple portion scalings, to produce a shape similar to an almond.
From there, I used intersections of elliptical cylinder sections, to create portions of the almond to "cut-away." I performed similar intersections with the inner "more-spherical" group.
I didn't get an exact reproduction, on this first attempt, but the exercise does demonstrate that 3D modelling should be manageable, using such methods.

By the way, Fresco seems to like ellipsoid & "almond" shaped buildings, boats & aircraft for his designs.
Do a "Jacque Fresco" Google Image Search for plenty more examples.
(The second image reminds me of a roach -- the bug kind, not marijuana.)
-
Excellent interpretation, of course, Taff! I realized later there was a sphere somehow off-center in the shape. I guess you have to scale parts of the almond leaving the intersection with the sphere untouched?
-
Yep,
Keep a vigilent eye, to make sure the edges shared by the 1/4-sphere and the 3/4-almond are not compromised, during scaling operations. Then the two groups will merge smoothly, when exploded.
BTW, I can see how pjbazel's interpretation, of the backside, may be correct. It may, indeed, be asymmetrical, unlike the "roach" house design.

I got the bug to play with this some more.
I wanted to use an elliptical and sperical shape both squashed. I don't know how to exactly draw an elliptical sphere, but I did both with follow me. I used distorted spherical and cylindrical shapes to cut out parts using solid tools. I ended up having to use Artisan to subdivide the shapes some more because the boolean cuts were coming out jagged. I used joint push pull to add thickness.
My ellipse shape is too long-- so they have more patio space. and the rest is still not like the original shape. Came away impressed by Fresco's imagination with organic shapes, and his drafting and modeling genius. I see now how the original drawing's deck appears to rise at the back. It's a natural illusion.

Nice!!
I took my eyes of this thread, didn't think it would see anymore action, but then I come back and wow! Nicely done guys!
Taff: Yes, Fresco, that's where I got the image! I took a screen capture from something I saw on youtube and then forgot where it came from. He's far out! lots of inspiration for modeling. Its funny to think that he uses those little plastic models to communicate his ideas rather than 3d models and renders. They look so dinky, hehe.
Great techniqe Stretching half of the sphere to get the almond shape, while melding with the proper sphere great idea. Ill have to play with that one and try to duplicate it.
also, leave it to the guy with the spinning geodesic as his avatar to make a weed joke...hahahah classic!
**pbacot:**nice refining of the techniqe, thats the closest yet, and who wouldnt want a little extra porche!
Thanks for playing along guys.......I knew there was somthing interesting about this shape, glad to see it gave you a bit of a bug too.
