IUs are not very easy to handle, and currently I am not very happy by the way they are handled. About the GAL layer, sorry, but I am not a GAL specialist. However I just know this issue is serious and must be solved. Until now, GAL was used only by Pcbnew. Unfortunately, in a few places, I saw a conversion to nanometers using fixed scaling factor. (A golden advice I learned when writing Kicad code: do not use a fixed scaling factor in code) Now GAL is very near to be used by other applications. Conversion to nanometers just by using a fixed scaling factor is therefore a bug, and from my point of view, even in Pcbnew. Who know: we could change one day the internal unit value. It already happened. I just leave guys who have a good knowledge of the GAL code taking the best decision. Thanks, John. -- 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
