Could you build this?

No Writing a full CAD kernel and interactive constraint solver in the browser demands specialized geometric modeling and computational geometry expertise.

What it would actually take: A browser-based CAD system requires a boundary representation (B-Rep) modeling kernel (or compiling OpenCASCADE to WebAssembly), an integrated geometric constraint solver, and efficient WebGL/WebGPU rendering pipelines. It demands deep mathematical domain knowledge in NURBS, topology, mesh generation, and numerical methods for non-linear constraint solving.
