Thanks = for the info. I figured pcb-rnd could probably handle this = situation.

Right= now however, I need to get a job done. I=E2=80=99d like to try = pcb-rnd as I've

followed the development for a = while but it feels like the =E2=80=9Ctrain has left the

station=E2=80=9D as far as I=E2=80=99m concerned. It looks = daunting to get started with and I

see no on-ramp = for beginners. Maybe for the next project.

Thanks again,

Roger

pcb-rnd allows polygons within footprint = elements, as well as lines and arcs, which, in combination with = terminals, can produce the sorts of structures you are playing with more = easily.

Importantly, there is also an "intnoconn" attribute that can = be used on copper features within the footprint

http://repo.hu/cgi-bin/pool.cgi?cmd=3Dshow&node=3Dintnoconn=

That can be used, for = example within a pcb spiral inductor, so that the copper does not look = like a short across the terminals.

With the gEDA PCB = footprint data model, you will have to paint the features with pads, = will end up with a short with DRC, and will have a limited ability to = manipulate the solder mask over the features, if needed.

Gang,
A quick question for PCB = gurus:

I have = a =E2=80=9Cfolded F=E2=80=9D antenna for 2.4Ghz. It has one open = end, one input for the signal
and one matching stub = that is to be connected to ground.

I drew this in PCB as a series of = =E2=80=9Cpads=E2=80=9D. I attempted to make one pad =E2=80=9C1=E2=80=9D = the input,
and pad =E2=80=9C2=E2=80=9D as = ground. gschem did not complain about the symbol, but PCB = complains
about not being able to find pad = "2" (the ground pin).

Could this be because PCB sees all the pads overlapping as = one pad? If so, how can
I overcome this = problem?

Thanks,
Roger Traylor
