Right, so then this option needs even more consideration, and perhaps the result will be not one, but two files for the automated stuffing machines. -a >> On May 10, 2015, at 10:24 PM, Andy Peters <[email protected]> wrote: >> >>> >>> On May 9, 2015, at 2:27 AM, jp charras <[email protected]> wrote: >>> >>> Le 09/05/2015 00:08, Andy Peters a écrit : >>>> I was just skimming the kicad.info forum and a person had a question about >>>> why some parts did not end up in the position file needed for assembly. >>>> Another thread mentioned that that can be handled by setting an >>>> “attribute” for each part in pcbnew.
