Wayne,

After my quick look at JP's custom pad code, I think the patch is still
valid simply because it allows for the quick conversion between copper
layer graphical items in an Eagle footprint to the equivalent KiCad item.
Eagle Cad does not have an equivalent custom pad shape feature which groups
graphical items as a pad within the footprint. As JP mentioned the
conversion to a proper custom KiCad pad shape would be non trivial. I have
seen Eagle users, use multiple graphical elements on separate layers to
define a pad, e.g. A polygon for copper, another for paste, another for
mask, and sometimes these do not overlap completely. Which if I assume
correctly is not supported by a custom KiCad pad?

I'll  find some Eagle boards with custom footprints (mostly antenna's) to
show how its being used.

Regards
Russell
