You can create nets automatically from your traces. This is useful if you created a circuit design by laying traces without first creating nets. This is useful especially prior to rearranging a board layout as the nets will automatically help you avoid errors while rearranging components. The nets will also allow you to use the PCB auto router to perform or help with the rearrangement.

alt To Create Nets from Traces:
  1. Click Nets | Create Nets from Traces. Pad2Pad will scan the board layout and create nets. A dialog will appear to inform you how many Nets were created.
  2. Choose Nets | Edit Nets... to review the created Nets. The Nets will be named "Auto01", "Auto02", etc.
  3. Typically you would then enable View | Layers | Net and then proceed with rearranging your circuit board layout.
