Multi-Page PDF Underlays
Choose and change the page displayed by a PDF underlay.
A PDF underlay retains the source PDF and displays one page at a time. You do not need to reimport the file each time you want to inspect another sheet.
Choose a page during import
Load the PDF through Import → Underlays. For a document with multiple pages, use the page arrows in the workspace to move to the sheet you need. Then adjust and calibrate that page before creating the underlay.
Change the displayed page
Open the underlay controls in Layers. A multi-page PDF shows Page, previous/next buttons and a page-number field. Enter a valid page number or use the arrows; wait for the page to load before another switch.
Check the page’s scale
Page-specific crop and calibration can be retained. Different sheets can use different scales and orientations, so verify a known distance on the page you are using. If a switch fails, the control continues to show the page that actually remains loaded.
