01
Annotate plan sets clearly
Use text, arrows, callouts, shapes, stamps, and comments to make scope questions and review notes visible on the sheet.
02
Measure after calibration
Set scale once, then measure and count directly on the PDF so notes carry useful quantities with them, or take it further with a full construction takeoff.
03
Share the marked-up PDF
Export clear marked-up drawings for coordination, internal review, client communication, or downstream estimating.
04
The PDF specifics that matter on real plan sets
Construction PDFs are not office documents, and the handling shows: drawing files upload at up to 500 MB each, scanned (raster) sheets are supported alongside vector PDFs — calibration works the same on both, since scale comes from your reference dimension rather than embedded metadata — and exports keep markups as crisp vector content by default, with flattening to raster available when a recipient's viewer mangles layered annotations. Very heavy sheets render through server-side tiling, so a 200 MB scan set still pans smoothly in the browser.
