Unlike traditional CAD software where you draw with a mouse, every object in this collection is "baked" from Python scripts using the CadQuery framework. Instead of static files, these are living algorithms that can generate infinite variations of a design just by changing a few variables.

Why Procedural CAD?

  • Precision through Logic: Geometry is defined by mathematical relationships, ensuring perfect symmetry and alignment (e.g., in the Hyperboloid Lattice).
  • Infinite Scalability: Need a staircase with 10 steps or 100? Just update the n_steps parameter and the model rebuilds itself instantly.
  • Algorithmic Creativity: Some shapes, like the Voronoi Shattered Cube, would be nearly impossible to model manually, but are simple for a well-written script.
  • Version Control Ready: Since these models are code, they can be tracked, branched, and improved using Git, just like any other software project.
