I’m a first-year architecture student working on a chair design project. Our final deadline is this Friday, and we need to produce a full-scale model by Tuesday. I’ve already sketched and modeled a parametric concept for the chair and tested fabrication methods, but I don’t know Grasshopper well enough to build the digital model parametrically. I need to model it in Rhino so we can finalize dimensions and prepare for full-scale fabrication.
I’ve created diagrams for the top view (figure 1) and elevation (figure 2) that show the geometry we’re working with. The form is based on a diamond shape: the bottom third curves upward at 15 degrees, and the top third curves at 135 degrees. We built a 1/4-scale chipboard model (figure 3) using a slit‑based fabrication method, but for the final model we want to switch to an egg‑crate system similar to the references in figure 4 and 5. We only want the armrests to use the egg‑crate structure; the geometry should flatten as it approaches the center.
We also need to design a base that fits beneath the diamond form using cut panels, similar to the example shown in figure 6.
If anyone could guide us through how to model this in Rhino—or recommend a Grasshopper workflow or plugin that would help us generate the egg‑crate structure—we would really appreciate it.
