    • Tap the Compare this drawing header.

    • Tap the drawing or revision that you would like to compare.

Troubleshooting (realign sheets)

If your drawing appears to have every line highlighted in red and blue, your PDFs may have been shifted a few pixels when the revision was created (see example below).


  1. Tap Adjust Alignment icon-adjust-alignment-android.png.
  2. Select a region of the drawings you want to focus on.
  3. Tap Confirm.
