If you?re a PCB electronics designer, you know how important it is to review your designs thoroughly before sending them to manufacturing. It?s costly ? and embarrassing ? to find design errors in a production board.
You also know how difficult it is to really check everything in CAD. You?re dealing with multiple layers, so you can?t see everything at once. Plus, your CAD program generates some structures automatically ? you don't see them while you?re in CAD. So it?s hard to visualize your finished board.
