I fixed that in rev 5531. For NPTH pads, the rule is: Pads are not draw on copper layers (in GERBER plots) when the hole has the same size, shape and position as the pad. Reason: Avoid artifacts like this one. -- Jean-Pierre CHARRAS _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
