PDF Frames

Read, search, and navigate multi-page PDF documents in Frames.

PDF Frames let you read and work through multi-page documents without leaving Refbox. Each Frame remembers where you were, including the page, position, zoom, and rotation, so you can pick up where you left off.

Page Navigation

Use the toolbar at the top of a PDF Frame to move through the document:

Arrow Buttons
Click the left and right arrow buttons to move to the previous or next page.
Page Number
Enter a page number to jump straight to it. The total number of pages appears alongside it.
Scroll
Scroll through the document normally. Refbox updates the current page as you move between pages.
Use the page number field to quickly jump to a particular page in a long reference document or design spec.

Zoom and Rotation

The PDF toolbar includes controls to zoom out, fit the page to the Frame width, and zoom in. The current zoom level is shown between the zoom buttons.

Use the rotate button to turn every page clockwise in 90° steps. Your zoom level and rotation are saved with the Frame.

Hold Cmd on macOS or Ctrl on Windows while scrolling over a PDF to zoom toward the pointer.

Find Text in a PDF

Press Cmd+F on macOS or Ctrl+F on Windows while a PDF Frame is focused, or select the search button in its toolbar. Type a word or phrase to find it throughout the document.

Refbox highlights every match, shows the current match and total number of results, and takes you to the selected result.

Next Match
Press Enter or select the down arrow to move to the next result.
Previous Match
Press Shift+Enter or select the up arrow to move to the previous result.
Close Search
Press Esc or select the close button to dismiss the search bar and clear its highlights.

Context Menu Actions

Right-click a PDF Frame to access:

Save As
Export the PDF to your computer.
Lock
Lock the Frame to prevent keyboard or mouse interaction.
Reset
Return the PDF Frame to the first page, its default zoom, and its original orientation.
Frame Docs
Open Frame specific documentation in your default browser.
Close

Tips and Best Practices

Jump to a specific page by entering its number in the toolbar.
Use search to find a term across a long document, then use Enter and Shift+Enter to compare each result.
Create multiple Frames of the same PDF Asset to compare different pages or details side by side. Each Frame keeps its own view.

3D

Import, view, and inspect 3D and CAD models in Frames.
