John Luciani has written a document proposing a footprint naming convention based upon IPC-7351. His doc is available for download here: http://www.luciani.org/ I believe that his footprint library follows his doc's convention. > Renaming the landpattern in the pcb (newlib) will probably follow some = > day. Renaming the footprints may cause havoc with existing designs. I wouldn't do it. Rather, I'd do this: 1. Add the new footprints/footprint names to the newlib dir. 2. After one year, move the old ones to a separate directory called newlib-oldnames or some such. Then, folks needing the old footprints/footpritn names can place this dir first in their gsch2pcb search path. > I always wondered why the pcb element names in the library (oldlib or = > newlib) do not conform to this IPC standard. PCB is an old program. The standard has only appeared recently. FWIW, plenty of commercial simulators don't follow this standard. Stuart
