Could you build this?
No A complete browser-based 3D CAD application requires complex computational geometry kernels (B-rep, boolean operations) and specialized WebGL/WebGPU graphics programming.
What it would actually take: Requires compiling an industrial boundary-representation geometric modeling kernel (like OpenCASCADE via WebAssembly) or writing a robust CSG engine from scratch in C++/Rust, paired with Three.js/WebGPU for rendering. Implementing parametric sketch solvers and topologically consistent CAD geometry requires advanced computational geometry mathematics that cannot be vibe-coded.
