In fact, net ties (not yet really supported by Pcbnew, but there is a workaround) and complex thermal pads are using pads, not vias. In Kicad, vias are track segments, and pads are managed by footprints, therefore are managed by a schematic, from the point of view of netnames. I know some EDA tools (and users) do not make always a lot of difference between vias and pads, but this is not the case in Kicad. They are 2 fully separate entities. -- Jean-Pierre CHARRAS _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : kicad-developers@lists.launchpad.net Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
