Redline the whole set.
The desktop PDF app architects, engineers and builders use to review, mark up and measure drawing sets. Quick on an 800-sheet issue, at home with the markups your consultants send, and your drawings never leave your machine.
One set. Every trade
that draws on it.
Architecture, structure, civil and every building service work on the same set. ScaleSet PDF gives each discipline its own tools on its own ribbon tab, and lets them all mark up the same drawing.

Open sheetBuilt for the
800-sheet set.
A construction issue runs to hundreds of megabytes of dense linework. ScaleSet PDF reads only the sheets you look at, and only the part of the sheet you can see.

Markups that travel.
Both ways.
Every consultant on a project uses a different app. ScaleSet PDF opens the markups they send as markups, and saves its own as standard PDF comments any reader shows. No export, no sidecar file, nothing lost.

What we keep
- Your email, name and team

Asked often.
Who is ScaleSet PDF for?
Everyone who works in a drawing set: architects, structural, civil, mechanical, electrical, hydraulic and fire engineers, estimators, builders and document controllers. Each discipline has its own tools on its own ribbon tab. Find yours.
Will it open the markups our consultants send?
Yes. Markups made in other PDF review apps open as markups - clouds, callouts, measurements, layers and groups - and ScaleSet PDF saves its own as standard PDF comments that other apps read. PDF compatibility.
Do my drawings get uploaded anywhere?
No. ScaleSet PDF is a desktop app; drawings are opened and saved on your computer. The licence check carries only your session, which computer holds your seat, its name and the app's version. Security and privacy.
Is it free?
Reading is: anyone can download it and open, search and print drawing sets. The markup, takeoff and editing tools are licensed to teams, a seat per person, one computer at a time. Teams and licences.
