I create a dir for each part (heavy symbol) with a big awkward name including some characteristics and a trailing distributor part number. Inside go symbol and footprint or whatever scripts or links to scripts generate them and a link to a Makefile that contains all the generic build logic common to all parts. It includes targets to export links to its parent dir, so parts can either be worked on individually and copied around or exported for use in designs. > What is the smoothest time saving way? Probably not mine, but it does work and gives good reproducibility of parts, boards, and BOMs (via some trivial script). Britton
