Editorial interest 78/100 Selection signal · not a rating of the site

A browser-based takeoff tool for pipelayers and drainage professionals who need to measure runs, chambers, and bends from drawings.

Landing page captured for the 2026-09-13 issue.

Field notes

The workflow is deliberately compact: choose a drawing page, establish scale, then trace runs while lengths and totals recalculate. The page says PDF pages are rendered locally at 1400–3000 pixels wide, while saved projects use short-lived signed links and row-level security. Free usage includes PDF reports, CSV export, and an XML file for estimating systems, all with watermarks; customer sharing begins with the Pro tier.
