BlueTraceAI is a desktop takeoff workstation for commercial MEP estimators, starting with HVAC ductwork. It helps review dense drawings by separating reading from measuring: Meta models interpret focused drawing crops and answer questions about the takeoff; local Python code extracts vector linework and calculates lengths from a verified sheet scale. Proposed quantities go to a local SQLite ledger for estimator review. If the scale is missing or conflicts, the quantity stays flagged instead of being guessed. The demo shows drawing intake, discipline layers, point-of-need reading, vector-based duct measurement, the review ledger, and evidence-linked copilot answers. Built by an individual developer for the Meta Global AI Developer Hackathon. Interactive walkthrough: https://weslyjohn1307.github.io/BlueTrace/
