Description
I had a hard time figuring out CAD software like Fusion, OnShape, etc., and decided to go about making my own CAD modeling software that I can "program" my models similar to how I think about them in my head.I used Cursor to write like 95+% of this, giving it my YAML examples and making it implement the actual code to make those work.Currently 100% self-hosted, and it is just a static HTML/CSS/JS, so it might just work without running npm at all.Very few features working currently, basically just modeling a few primitive solids, and boolean operations.

Could you build this?
Yes The author explicitly created this browser-based YAML-driven CAD tool using Cursor (vibe coding) to map declarative configs into standard WebGL/Three.js primitives.
Discussion
20 comments analyzed.
Competitors mentioned: OpenSCAD, ImplicitCAD, Antimony, TinkerCAD, BRL-CAD
Concerns raised: Missing core CAD features (PMI, views, simulation, units, materials, product structure), Fillets implementation broken/blowing up, Should be called 3D modeler not CAD software, Maintenance/resource sustainability unclear
Feature requests: Better fillet handling, Edge definition and filleting in code, Unit handling, Material properties support
