I am using the nanometer build without issue. (My only suspicion is with respect to grabbing zone borders with the mouse pointer. I have felt for some time that the hit testing there should use pixels to measure acceptable distance, not IU which are subject to variances on zoom factor. Pixels are not subject to zoom factor. Its in the TODO.txt file. It is painfully hard to select a zone boarder reliably in the nanometer build.) I like the idea of forcing folks to smoke out problems. Because it has to happen sometime. There are no beta testers on some kind of payroll. Pcbnew files (even legacy format files) created from that point forward are not compatible with the deci-mils build. So it is a bridge which is difficult to traverse backwards across. I've found that the Eagle plugin needs the nanometer build to avoid rounding errors, because coming from metric to deci-mils is and has been a problem regardless of plugin. This was the whole impetus to move to nanometers as a means of avoiding rounding errors even within legacy files in the first place. The fork in the road looks like this: a) change now, generate a bunch of new mm based footprint libraries and mm based legacy board files, which are not compatible with deci-mil builds. b) wait until the *.kicad_pcb files and s-expression footprints are fully supported, those will only ever be in mm, meaning this is mandatorily the nanometer build. Legacy files generated from this build are also not compatible with deci-meter builds. a) and b) both have the same disadvantage. I have personally chosen to go the a) route, because I can get more accurate footprints and boards in play now. I never have to use an older version of the software anyway. I cannot speak for other users, only for myself, and for the benefits to the project. Mostly we might be speaking about new users being affected by your change to your script. For them I might be inclined to lean towards a) also. If there was a pause point in the script's execution, or a way you can explain how to change from the default of nanometers to rebuild, that might be enough to make everyone minimally grumpy. On balance, I find your suggestion more positive than negative. _______________________________________________ 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
