Alas! If your are talking about painting zones by segments, like the filled (painted) zones shown by your images, this is a very bad idea: * This is inefficient because it can create *a lot* of segments when the minimal thickness is low (solid polygons are much more efficient). * This is prohibited by Gerber file format: see chapter 7.7 of the current gerber file format specifications (freely available from Ucamco): Here is what this doc say: "Painted areas and pads are not suited for PCB fabrication. Sending files with painted to a PCB fabricator is quite disrespectful." * For these reasons, this feature was removed from Kicad code some time ago. If cr5000 software uses only painted zones, this is really a bad idea. Now adding thick arcs in zone outlines to replace rough arc approximation for a better shape is an other problem: It could be a really good idea. However I am guessing this is not so easy to code. -- 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
