PMD 200 is a laser-based tool used to transfer locations from an architect’s drawings to reality on the construction site. Unlike traditional tools, the PMD 200 removes many manual measuring tasks required to mark the location of internal walls. This not only speeds up the process and removes scope for error, but makes complicated geometry (like curved walls) more accurate and economical. Controlled via a tablet, tasks are guided step-by-step via an interface designed to feel intuitive for any smartphone user. Ultimately, PMD 200 has turned an error-prone, two-person job into a faster, one-person task and made ambitious designs realizable.
