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.

Box one symbol and PolyPDF finds the rest — 17 matches on this sheet, each one reviewable before it joins the count. Committed counts land in the takeoff worksheet with a running per-subject tally, ready for CSV or PDF export.
Calibrate once — from the title block or off any line you know — then pull areas, lengths and counts that read in feet and inches. This sheet: 5,485 sq ft gross, two wall dimensions, a 17-piece diffuser count, all totalled in the worksheet.

Cloud the change, attach the RFI, and every markup lands in the Markup Table with status, author and date — so nothing you flag gets lost between review rounds.

Set scale from the title block or calibrate off a known line; every measurement reads in real units and the active scale stays pinned in the status bar so you always know what an inch means.

Four MUTCD sign series ship built in — Regulatory, Warning, Temporary Traffic Control and School — as crisp vector stamps. Search the chest, drop an R1-1 straight onto the sheet, and it prints as true linework.

Type a location, pick the CAD Linework style, and the map arrives inked like a drafter drew it — paper-white ground, black linework, live zoom and styling before and after it lands.

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.
Markup, review, calibration and Visual Search auto-count stay free for as long as you want them. The only wall is the fourth hand-created measurement in a document. That is the moment Pro is for, and it costs $49.99 once.
