First of, I have not followed the discussion about the NanoMeter. I do have some remarks. >From an engineering standpoint the NanoMeter makes little sense to me. If the smallest item represented is a nano-meter, in a 32 bit integer this means the largest board can be only 2.14 meters in size. (-/+ of the origin) >From my viewpoint this is not enough. (I know of CNC machines much larger than 2 meters) I have seen boards (radar systems and backplanes of 60 layers) which do not fit in there either. However I have never seen boards which require a resolution of more than 8000 dpi in photoplotting. All systems which I have seen in measurement (CNC and photoplotting) are not more accurate than 0.5 micron (0.5 * 10e-6 m) I would propose the internal resolution to be *10 nano meter instead of 1 nano meter which would result in making designs larger than about 2 meters and no significant loss of resolution* related to PCB design and production. Just my view on things, Have a nice day Edwin van den Oetelaar _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
