Sounds good. I like the idea of two layers that can be merged, or just use one. But really what I want is footprints that include the vias and some traces and middle layer copper that extends to make a heat sink, etc, all in the footprint! For future, not tomorrow... I figured why I did not see my qf.awk changes have effect -- not thinking -- I was only changing /modatabig/src/pcb-rnd/trunk/pcblib/parametric/qf.awk when I needed to be changing the installed place: /usr/local/share/pcb-rnd/pcblib/parametric/qf.awk Thanks for the changes! > >> I don't seen any lihata name=vlaue pairs in the .pcb file yet.

I'll save as .lht next and test that out.
