4 point polygon + 4 segments give the same filled shape (with a width = 2*aClearanceValue). However this is not equivalent when you have to combine this shape with other polygons (for instance using this shape to make a hole in a ground plane) or show an outline (sketch mode). The final result is a single polygon, which can be combined with other polygons in calculations. This is not possible with 4 point polygon + 4 segments. -- 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
