Align PDFs with Overlay Pages in Revu 20

Applies to:

  • Revu 20

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.

If you're overlaying drawings that vary in size and scale, you can align them with the Align Points option within the Overlay Pages dialog. Here's how:

  1. Go to Document > Overlay Pages, select the files via Windows File Explorer, and select Open. If the documents you're comparing are already open in Revu, they are automatically listed in the Overlay Pages dialog. To overlay additional files, select Add.
  2. (Optional step) To add a specific region of a drawing instead of the entire page, select Select Region in the Add Layer dialog and select the area of the drawing to include in the overlay. If a document is already listed in the Overlay Pages dialog, select Modify to select the specific region.
  3. In the Overlay Pages dialog, select Align Points.
    To ensure that the alignment points you select overlay accurately, select View > Snap to Content.
  4. Select three points in the first drawing. To cancel the manual alignment and return to the Overlay Pages dialog, press Esc.
  5. Select the same three points in the same order for each subsequent drawing. We recommend choosing alignment points from corners of the actual PDF content instead of from the borders of the entire drawing.
  6. Select OK. A new and properly aligned file named Overlay opens.
