Align PDFs with Overlay Pages in Revu 21

Applies to:

  • Revu 21

Overlay Pages allows you to merge PDF content from two or more files into one PDF that highlights the differences between the files in different colors. This feature is useful when you want to compare original and revised drawings, or when you want to view various building plans (e.g. electrical, HVAC, plumbing, etc.) layered in one PDF.

  1. Go to Document > Overlay Pages. The currently opened document is listed in the Overlay Pages dialog. To add additional files, select Add Files, and select one of the following:
    • A file from the list of opened files
    • Add Files to use the Windows File Explorer to browse for and open a file
    • Add Open Files to add all files currently open in Revu
  2. (Optional step) To add a specific region of a drawing instead of the entire page, do the following:
    1. Select the file, and select Edit Layer.
    2. Select Select Region, and select the area of the drawing to include in the overlay.
    3. Select OK.
  3. In the Overlay Pages dialog, choose the alignment method:
    • Page Align: By default, Revu places your PDFs directly on top of each other. Recommended for drawings that have minor revisions but are otherwise the same in terms of scale and position on the page.
    • Auto Align: Revu automatically finds points of alignment between your PDFs. Recommended for drawings that vary in size and scale.
    • Manual Align: Revu allows you to select three points that will act as anchor points between the drawings. You must select the same three points in the same order for all your selected drawings. Recommended when Auto Align doesn't work as intended.
    To ensure that the alignment points you select overlay accurately, select View > Snap to Content.
  4. Select OK.
