These people actually have a piece of software just for editing information about a PCB's layer stack... worth a look. http://www.ida-step.net/components/editors/pcb-layer-stack There is also some useful and interesting stuff about electronics in this document here (found from the wikipedia article) http://www.tc184-sc4.org/SC4_Open/SC4_Standards_Developers_Info/Files/STEP_application_handbook_63006.pdf Look around Pages 150,159, http://www.ap210.org/tiki/tiki-index.php http://www.ap210.org/tiki/tiki-index.php?page=STEP-Book+AP210 Lots of good stuff here: http://www.wikistep.org/index.php/Main_Page And: http://www.steptools.com/support/stdev_docs/express/ap210/html/index.html Seems like this is stuff people are working on "right now", as far as software support is concerned. It seems a shame the standard is so damned huge, and not freely available. Down with non-free standards!
