I Need assistance making an etfe roof/ ideally in triangular of quads. I dont necessarily have problem making the space frame truss underneath just not sure how to get the initial start to making the bubbles for the etfe roof. Any assitance would be great.

ETFE (Ethylene Tetrafluoroethylene) roofs are lightweight, highly transparent, and durable, making them popular for stadiums, botanical gardens, and atrium roofs.
Hi @Quin,
Does this earlier post solve what you are after?
Ive tried using that for help but Im not very experienced using grasshopper let alone kangaroo so im kind of stumped. I was able to get a triangulated grid on my surface/mesh however, Im not entirely sure how to take that grid and apply the pressure component to inflate the mesh. If you are experience or would be able to help I have attached my file and code that I have so far.

Just from an architectural/design standpoint: why are you using a triangular grid? That makes no sense.
Im honestly going based off my what my professor instructed he said to either do tri or quads. I dont necessarily need a triangular grid. My plan was to do iterations of different grids, and ultimately use that for what is most structurally and financially reasonable.
He also mentioned if I were to use kangaroo typically triangulated would work better because they dont shear, however as I was looking for information it may be easier to do a more rectangular grid and use weaverbird quadremesh.
You have a rectangular base. The underlying structural system will be directional because it is not square. Strips of pneus will be simpler, more financially feasible than many, small individual cells. Just like in your example picture. You have linear strips of pneus going along the shorter dimension of the space frame. No need to discuss that later, you can already know that now. (The construction in the image isn’t really a space frame.)
If you are desperate for alternatives to show, show a quad grid. Or show bands, quad grid, triangular grid, I don’t know. They can all be constructed similarly anyhow.
