What you can do on day one
Designed for architects, engineers, contractors, estimators, and reviewers working from PDF drawings.
Set the scale once and take distance, area, and angle measurements directly on the PDFs your team already uses.
Add callouts, highlights, shapes, and notes so site issues, design comments, and decisions are easier to communicate.
The free download — Mac or Windows — lets you test PolyPDF on live work before you unlock unlimited hand-created measurements.
Counting, measuring and drawing review — the work you actually do all day — across three disciplines of one project. Captured from the shipping app, not mocked up.

Drop a marker on each symbol and the takeoff worksheet keeps a running tally per subject, right beside your areas and lengths. Number the marks as you go, then export the whole worksheet to CSV or PDF when it is time to price the job.
Calibrate to the printed scale once — presets for the common architectural scales, or dial in your own, metric or imperial — then pull areas, lengths and perimeters that land directly on the drawing. No CAD file, no re-drawing, no math on a notepad.

Revision clouds, leader callouts, stamps and highlights, with text sizing you control — so a note that reads on screen still reads on a printed half-size set. Every markup is tracked in the markups list, so nothing you flag gets lost between review rounds.

AEC teams deserve tools built for the machine in front of them. PolyPDF runs the same engine as a real desktop app on macOS and Windows, focused on the everyday review, markup, calibration, and takeoff workflows construction PDFs demand.
The Mac DMG and the signed Windows installer ship the same engine at the same version — open drawings directly, no VM or browser-only workaround on either side.
Distance, area, perimeter, angle, count, and dimension tools are built around the PDFs architects, contractors, and estimators already exchange.
Try real documents for free, then unlock unlimited hand-created measurements with one direct license that covers up to 3 computers.
The free download — Mac or Windows — handles review and markup. Pro removes the measurement cap for $49.99 once.
