I'd never have thought of using steel cables tbh, do they not cut into the lattice ?
Not a criticism Mike, just genuinely interested; seriously thinking of having a go at a geodesic dome since I know I don't have room for the yurt and it's poles in my car.
cheers,

Steel cable won't really cut in any more than heavy rope - either natural or nylon. Yes, it would be better to have a flat and wide strap. That spreads the "pressure points" out. But there should be no extra worry on each piece of lattice - do to the sharing the force over many smaller areas. The more pieces of lattice that are being held in by the tension band, the less tension on each one individually. If it becomes a concern, you can always put a small metal plate on top of the individual laths to help spread out and resist the pressure.
A geodesic dome? TINKERTOY HEAVEN! Yes, you get lots of small or short pieces, but spend more time fitting it all together - even with some sections left whole in transit. They are great in bad weather, and very strong. But one note: when you go larger than that half-sphere, you start losing floor space while gaining extra "head room" that is hard to utilize.
I did a little research on modern interpretations of yurts a few years ago - as in building them yourself, and to use as permanent homes and shops/offices. I really liked the Concentric Yurt - a 12 foot diameter yurt built up on a raised deck 7 to 8 feet high, and then with another whole outside wall/roof running all the way around it - a 20 foot diameter. The outside walls were made of solid boards, leaned outward, and had benches built in all around them for sitting and storage. You ended up with that large round room on the "second story", the room underneath that room/deck for household utilities (kitchen and bathroom), and that outside ring to use for bedrooms, office space, storage, running track for kids, etc.
And then there was that LOG yurt. Interesting buildings indeed!
And they can make pretty fun temporary tents. If you drill and rivet your laths carefully, you can make them in short sections that can be folded up pretty small - kind of like an accordian, or a kid's safety gate to put into a door. When you pull them apart to expand them, they become fairly easy to bend/curve into a section of your circular wall. There should not be any need to "pre-bend" things. The biggest pieces to worry about are the door and its frame, and that central "wheel".
That central "wheel" in the peak ends up being a matter of personal choice. It's nice to have it big enough to act as a skylight. But that comes with a lot more bulk and weight in packing. Some people just have a small hub to set the ends of their roof poles in, and then cover over it completely with their canvas roof pieces. But most have that larger "wheel". And if they want to put a stove inside, it makes a good place to run the stove pipe up through.
There is/was and old book put out years ago by the people who wrote up the Whole Earth Catalog - called Shelter. It has a lot of good info and contacts on all things concerning shelter - temporary, traveling, and permanent. Because of how old it is, some of the contact info probably is no longer valid.
Yes, I do like yurts - in the right situations. Ditto my tipi.

p.s. I love your ... flexible rivets ... for holding the laths together! And so simple - just nylon cord knotted, and run through a hole in each board. Loose bolts or iron rivets might give you a tad more strength, but they add to the weight and decrease the "flexibility".
