Enginuity is an AI-powered parametric CAD application that lets users create 3D solid models through natural language and engineering drawings — instead of manually operating traditional CAD software. The problem: Traditional CAD tools (SolidWorks, Fusion 360, etc.) have steep learning curves and require manual step-by-step modeling. Translating an engineering drawing or a verbal idea into a 3D model is slow and skill-intensive. What Enginuity does: - Chat-to-CAD: Describe a part in plain English ("create a flanged bracket with bolt holes") and an AI agent executes the full build123d modeling pipeline — sketch → extrude → fillet → booleans — producing a live 3D solid in the browser. - Sketch/Drawing-to-CAD: Upload or AI-generate an engineering drawing, and Gemini vision extracts the 3D feature tree (extrusions, holes, fillets, chamfers) with real dimensions, then the agent builds the model automatically. - Live feedback: Real-time 3D rendering in Three.js as each tool call completes, with a full agent trace panel showing the modeling pipeline as it executes. Stack: Next.js frontend, FastAPI + build123d Python backend, Gemini for vision/reasoning, Vercel AI SDK v6 for agentic tool calling, Three.js for 3D rendering.
