Drawing Agent - Engineering drawings → mm-accurate, editable 3D CAD

Hi Product Hunt! 👋 I'm Yusuke, founder of Renue. We've been working with manufacturers — industrial motor makers, sports footwear brands, civil engineering firms — and they all hit the same wall: turning legacy 2D drawings into editable 3D CAD takes 1–2 weeks of CAD operator time, and the operators are scarce. Most "AI 2D-to-3D" tools generate the model once and let humans patch the rest. Drawing Agent does it differently: 🔁 It writes CadQuery / build123d Python code, renders the result from 8 angles plus cross-sections, then asks Gemini to compare every render against your original drawing. If the quality score is below threshold, the AI rewrites its own code. Up to 10 iterations — until it converges. 🧱 What you get out is a B-Rep solid (STEP / STL / GLB) that opens natively in SolidWorks, Fusion, and Inventor, with millimetre-accurate dimensions on every edge. The Python source is delivered alongside, so the model is auditable and re-runnable. 🟧 Multi-part assemblies are split per-part, with mate hints. Low-confidence picks are highlighted in orange so reviewers know exactly where to look — engineering review time drops by ~80%. We ship a free SaaS (3 generations on signup), an on-prem build for confidential drawings that can't leave your VPC, and a tuning track for company-specific JIS / ISO drawing rules. Would love your feedback — especially from anyone who has lived the "two-week CAD round-trip" pain. AMA below 🙏
