You can do this on a website, and that would be my preference. The interface to fetch the footprint into Pcbnew can be in C++ using a PLUGIN. The user goes to your website using a web browser to design the footprint, he gives you a user ID so you can remember the part and his name as soon as he comes back using Pcbnew to fetch the footprint a few minutes later. The http PLUGIN is a permanent entry in the new library table support that points to your site. The options field for this library table row has his user id. When he does a "list footprints" operation on that virtual (http based) library, he sees only one part, the one you just let him build. This is possible since the options data is passed into the FootprintLibEnum() plugin call. There is a website that does much of this already, what is needed is the PLUGIN and teaching the website to cache the footprint and associate it for a few minutes with the user id. Anyone can do this again, and better, using what did you call it, perele or something like that? _______________________________________________ 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
