ISONQ reads PDF, DXF, DWG, and STEP files on the shop's own workstation and produces a priced quote. Nothing leaves the machine. Three modules, one job: 2D Workspace reads the drawing. PDF and DXF/DWG in. Title block, dimensions, tolerances, threads, GD&T out. 3D Workspace enriches the geometry. STEP-native. Smart Measure, section view, feature detection. Shop Management turns both into a quote. Auto-populated, priced, sent. The only system that reads the PDF and the STEP side by side — title block, dimensions, tolerances, and the 3D model in one review. Stack: Tauri, Rust end-to-end, Ollama for the LLM layer that reconciles 2D drawings against 3D geometry. Runs on the shop's own machine. No per-drawing fees. No uploads. Live pilot at a Colorado CNC shop, v7.0.3 in production. Demo video on the linked page. Happy to answer questions.
