PDF Expert for iOS adds a powerful toolset for construction professionals

TL;DR. PDF Expert for iOS updates with much-awaited scale and measurement tools, polygon and polyline shapes, callouts, and more. Finally, it’s the only app you’ll need to work with PDF drawings and blueprints.

Thousands of architects, engineers, and designers rely on PDF Expert in their daily work. Our customers love PDF Expert for its speed, intuitive design, convenient file manager, and powerful annotation tools.

Yet, the product lacked some crucial tools to become a go-to solution for AEC professionals. Many of you requested scale and measurement tools to be able to fully rely on PDF Expert in your workflows. And we listened! After dozens of user interviews, long months of fine-tuning the product, and addressing the feedback of our beta testers, we’re excited to launch the construction toolset in PDF Expert for iPad and iPhone.

PDF Expert becomes the only app you need to work with PDF documents. Finally, you can ditch clunky industry-specific apps you used for measuring blueprints or drawing polygon shapes.

Get the latest version of PDF Expert, and let’s dive into details!

Scale and measure drawings

PDF Expert now lets you take accurate measurements on your plans, helping you with takeoffs and estimates. 

The measurement tools are available under the new Measure tab that can be added via the + button on the toolbar.

PDF Expert intelligently detects the scale on your plans, saving you time on calibrating them. You can also enter the scale manually or calibrate a PDF to a known dimension.

Once you’ve set the scale, you can easily measure distances, areas, and perimeters on your drawing.

Create sketches on the go

Help clients visualize a future room or building and sketch ideas right on your iPad. The new polygon and polyline tools let you draw rooms and furniture of any shape. You can enter the exact dimensions of the objects you sketch to be absolutely precise. Use hatch patterns to represent different materials and make your drawings easier to read.

The new shapes are located under the Draw tab, together with other useful tools like pens, markers, arrows, circle and rectangular shapes.

Review drawings effortlessly

PDF Expert makes marking up drawings easier and faster with the new annotation tools you’ve been asking for:

  • Cloud shape – draw attention to the areas that were changed or need to be updated.
  • Callout – add text notes pointing to a specific object on a page.

You’ll find all the tools you need for reviewing drawings under the new Red Line tab. Besides, PDF Expert is fully customizable, so you can create your own set of the tools you use the most.


The construction toolset is part of PDF Expert PRO for iPad and iPhone, available at $49.99/year, with a free 7-day trial. The subscription also lets you edit PDF text, images and links, sign documents, merge PDFs, and more. 

The existing PRO subscribers get construction tools at no extra cost.

Please note: the construction tools set is currently available on iOS only.

This update is our first step towards creating unique experiences and tools tailored for professional segments like lawyers, teachers, doctors, and more.

We’d like to thank everyone who talked to our team, helped us better understand your workflows, and provided invaluable feedback during the early testing. Our team sincerely hopes the new PDF Expert becomes an indispensable tool for your daily work.
