DuctCount, a mechanical takeoff tool in the browser

Field notes

The browser interface combines drawing navigation, scale calibration, and mark-up controls with a structured takeoff record. Duct entries can capture dimensions, measured and stock lengths, gauge, material, and insulation status, while items can be grouped into areas or rooms. The page also exposes Excel export and order-list generation. It is labeled a work in progress, and its instructions specifically request an engineered print rather than a photograph of one.
