A mark to help machines orient the package is enough; the machines don't care at all about pin numbering, only orientation. Pin numbering is only of interest to the PCB designer to ensure that tracks are routed to the correct pin; in most cases there is no useful purpose of indicating them on the board. - Cirilo -- Mailing list: https://launchpad.net/~kicad-lib-committers Post to : [email protected] Unsubscribe : https://launchpad.net/~kicad-lib-committers More help : https://help.launchpad.net/ListHelp
