The Match Manually dialog
The Match Manually dialog


The Match Manually dialog is used to choose whether to manually match nets if there are nets that do not match on both sides (between the PCB and schematic). 


The dialog is accessed in one of the following ways:

  • After updating a document when one or more nets are not able to be matched between the PCB and schematic. For example, it appears after a net name has been changed on the PCB or schematic, but the net name has not been changed on the corresponding design document. 
  • Clicking Manual Component Links in the Failed to Match Unique Identifiers dialog.


  • Don't Show This Again - click to not show this dialog the next time nets cannot be matched.
The state of this option is retained in the [Comparison Options] section of the project file. When Confirm=-1 the Match Manually dialog will display, when Confirm=0 the dialog does not display. Always create a copy of the file before attempting to edit it in a text editor.
  • Yes - click to open the Match dialog in which you can manually match any unmatched schematic nets to unmatched PCB nets.
  • No - click to remove the existing unmatched nets from the PCB and add the new nets that do not currently exist on the PCB. The Engineering Change Order dialog will open.
