I'm the only one with difficulties with gencad importers??? The original format is more or less rejected by everyone, I fixed it for gerbtool (the CAM used by our fabricator), but it comes wrong in CAM350... I'm getting crazy! it seems that every parser around has a different interpretation of the standard (which is, in fact, pretty clear)
Actually it seems that every importer around is not compliant (especially for back side components, someone flips the padstack on FLIP, someone else on bottom placement... and the standard says yet another thing!); gerbtool *needs* padstacks (which are officially optionals), CAM350 reads them but in the table they all are 'unused' (but at least the pads are right!) Anyway, I made the export work for *both* gerbtool and prontoplace (which apparently use the same parser) and CAM350, too.. except silk shapes which simply can't be done properly with both (CAM350 apparently only accepts closed outlines, prontoplace 'forgets' to flip them...); anyway these days gencad is only used as a netlist source for ATEs, so silks are not so important. When I find again the coding conventions I could submit a patch (i.e.: where are the coding conventions for kicad?:D) Another kind of netlist which seems widely accepted is the IPC-D-356 (there are also the 356-A and 356-B which are not compatible!); looking around it seems a pretty easily generated format (more or less a drill file with associated the net name); the only problem is the net name is limited to 14 chars... do we have a standard 'shortened' net name or I need to generate aliases for them? If someone else think it could be useful I can implement this. -- Lorenzo Marcantonio Logos Srl _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : [email protected] Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
