Add to the list: thermals/antipads for internal layers are often different from outer ones (and we don't have a 'formal' padstack support), so even these parameters should be per layer... (when you're at it, it is often useful to have thermals on THT pads and solid copper for SMD ones, for obvious manufacturing reasons...) I don't feel that a multilayer zone would be too useful (and I agree is *very* tricky to implement correctly). It's actually pretty easy to 'trace' over another layer's zone when creating a new one! I could suggest an UI modification in regard: when you're in 'add zone' mode, clicking on/near an existing zone corner shouldn't put you in 'edit zone' mode for that zone (otherwise you can't 'trace' from the first corner...) -- Lorenzo Marcantonio Logos Srl _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
