Could you build this?
No This tool performs rigorous, deterministic geometric dimensioning and tolerancing (GD&T) analysis against ASME Y14.5 without AI, parsing STEP/PDF CAD data and calculating 3D tolerance stacks and datum reference frames.
What it would actually take: Building this requires expert mechanical engineering and computational geometry expertise. The architecture demands a custom CAD kernel parser (e.g., OpenCASCADE or commercial CAD SDKs) to extract 2D/3D PMI (Product and Manufacturing Information) and STEP AP242 data, coupled with a formal rule engine encoding ASME Y14.5 mathematical definitions. Developing deterministic tolerance zone visualization and 3D stackup engines requires deep domain knowledge that LLMs cannot reliably synthesize.
