How to align PDFs with Overlay Pages

Applies to:

Revu 20

Revu Overlay Pages Icon 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 > Revu Overlay Pages IconOverlay Pages, and select the files via Windows File Explorer. Select OK.
    • If the documents you're comparing are already open, Revu will automatically list the files when the Overlay Pages dialog opens. To overlay additional files, select Add Open Files in the Overlay Pages dialog.
    • To add a specific region of a drawing instead of the entire page, click Select Region in the Add Layer dialog and click and drag your mouse across the area of the drawing that you want to include in the overlay.
  2. Select Align Points.

    To ensure that the alignment points you select overlay accurately, select View > Revu Snap To Content IconSnap to Content.
  3. Select three points in the first drawing.
  4. 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.
  5. Select OK.

Once you complete these steps, a new and properly aligned file named Overlay opens.
