Could you build this?
Partial The scripting language, IDE and UI can be vibe-coded, and the author reports building it. Exact B-rep solids with fillets and STEP export depend on a geometry kernel, which is hard to produce without CAD-kernel expertise.
What it would actually take: Use a scripting language and interpreter (Rust or C++) on top of an existing B-rep kernel such as OpenCASCADE, with a UI built on a 3D viewport and STEP/3MF/STL exporters. The hard part is robust boolean and fillet operations that do not fail on edge cases, along with unit handling and parametric regeneration. Computational geometry expertise and years of kernel-level debugging are required.
