Yes Mr. Huff :-), I think I posted it on Compuserve a few years ago
but not here.

Bingo! We have a winner. A door bell kit from Maplin many years ago to
replace one that got zapped by lightning.

Part numbers done with PSPro. The Cu track was scanned with a hand
scanner (hi-tech then), then used as a HF. Needed to accentuate the Cu
height for non-techies ;-)

A Logitech 4-bit BW hand scanner on the supplied schematic. Took 3
scan strips if I remember, then was image_mapped onto a bozo HF. 1-bit
coz 4-bits was way to large a file then.

That's right, and the onboard rectifier allows for battery or "bell
txformer" operation.

With the right tools nothing is impossible :)

Um, is this entirely within POV, or did you use an external utility?
("Cadstar"?)
I was referring to the difficulty of building this capability *into the
include file*. I'm aware there are other programs that can do it, but
doing it in POV-Script would be difficult. (though I can probably figure
out a fairly limited method...)

Couldn't you just break a spline down into linear segments?

No, I was suggesting how you could do the traces, using boxes and splines
broken down into linear segments... or am I totally lost?
