The best way to align drawings with Overlay Pages | Revu 2017 & below

Wish you knew the best way to get your documents aligned properly when using Overlay Pages?

To help you out, we’re going to cover some concepts that will further clarify this process.

Let’s look at a scenario where you have a drawing on a 42″x30″ sheet, and you want to overlay another drawing of a small section of the building, which is on an 8.5″x11″ page.

The basic procedure for overlaying documents is to select the files you want to compare, choose three alignment points within the actual drawing content of each file, and then run Overlay Pages to create a new file that contains a separate layer for each document. But to really ensure that the alignment points you select will properly overlay those files, you should enable Snap to Content.

Let’s look at the steps for overlaying the example files shown above:

1. Add the files you’re comparing to the Overlay Pages dialog box:

  • If the documents are already open, you can go to Document > Comparison >Overlay and the Overlay Pages dialog box will automatically list the files when it opens.
    If you have additional files open, you can add them by clicking Add Open Files.
  • If the files aren’t open, open Revu without opening the documents, and then go to Document > Comparison > Overlay to open the Overlay Pages dialog box, then click Add. This lets you locate and select the first of the files you want to compare. To add the rest of the documents, click Add again and repeat the process for each file.
But Wait…What If You Don’t Want to Include Everything?

What about the title block at the bottom of the 8.5″x11″ drawing? You probably don’t want that showing up in the final overlay file, so to exclude it:

  • Click the file (in this case “ASK-102.pdf” ) in the Overlay Pages dialog box, and then click Modify.

    This opens an Add Layer dialog box.
  • Click Select Region, then left-click and hold while dragging your mouse diagonally across the area of the drawing that you want to include in the overlay.
  • Click OK when the Add Layer dialog box reappears.

2. Picking Your Alignment Points:

When picking the alignment points, it’s important to pick the same three points in the same order on each drawing. But to improve the accuracy, you should switch on Snap to Content by clicking Content in the Status Bar or using keyboard shortcut F8.

You can also enable Snap to Content by going to Grid & Snap Preferences and clicking the Snap to Content checkbox.
  • So assuming you’ve enabled Snap to Content, click Align Points in the Overlay Pages dialog box, and click three locations in the first drawing. Once you’ve done that, the next drawing will open, allowing you to select the same three point in the same order.
    Ideally, you should select the Alignment points within the actual drawing content instead of clicking three corners of the surrounding border.
  • Click OK in the Overlay Pages dialog box.
    Once the process has completed, a new, properly aligned file called “Overlay” will open.

You can find more in-depth information about using Overlay Pages and Batch Overlay in the Bluebeam Revu Manual.
