Thanks to Orson and you. I tested this version with a few boards (basic and very complex) Time to fill zones and rebuild the 3D scene is roughly the same as the current version (sometimes faster, sometimes longer, but comparable). However, I have 2 boards where the copper zones filling does not work. (zones not filled) There is also issues when combining a cutout area with the existing outlines of a given zone: When the cutout outline intersect the main outline, the cutout area outside the main outline is filled. The cutout area outside the main outline should be removed: the cutout area is not a keepout, just the area which should be removed (subtracted) from an existing zone, and any area outside the initial zone should be removed. When a cutout zone is added to an other cutout zone and overlaps it (inside a main zone outline), the merging of these 2 zones is incorrect and gives strange result. This is easy to test using non copper zones. -- 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
