I have not found any specifications to any of the gEDA programs. Could
some one point me to them or answer the following questions?
How large a pcb layout can PCB handle? That is, how many layers, what
board size, how many pads and components?
How large a schematic can the schematic capture

About a quarter of a mile per side. Yes, I've done this, my house
looks *really* small on that scale.
Just for the fun of it, I just tried to set a huge board size.
I got bumped back to 30

I got bumped back to 30 inches on a side. This is from the
Preferences/Sizes GUI in CVS PCB-HID-gtk.
I believe you in theory, but something artificially reduces the range.
Two minutes grepping around in the source tree didn't

Try the lesstif HID. It doesn't have any of the arbitrary

If you don't mind editing one line of a .h file, as many as your
They all look like max bounds and probably should use the pcb's
actual width and height instead.
A 32-bit signed integer type is what limits you to 1/4 mile (er, 0.338
miles). If you need more than 0.338 miles on a side, yeah, you can
compile with long or long long but you'd have to go through

We only need about 18 inches X 18 inches and up to 24 layers. How about
ground planes? Does it also handle split ground planes?
Heretic! Ground planes are by definition not split!
Fortunately for you, PCB is agnostic on the subject.

At what point due to curvature of the earth would we be forced to move
from the cartesian coordinant system?
At 0.338 miles, the deviation due to earth's curvature is about a
quarter of an inch.
That doesn't mean we can't still build (or at least design) flat
things that big.
It would be SO nice to have gschem and/or PCB be able to use a
client/server component database. In fact I'm practically drooling
at the mere thought of it.

Hi, It's been a while since I've used PCB, but soon I'll be using it almost
every day again. I do some systems work for biologists that is paid with
dribbles of grant money, so I am studying how to use postscript artwork to get
better than 10 mil traces, or I will learn form Xultz how he does
I do homebrew image transfer boards with gschem and pcb. 15 mil trace expands to
about 20 mil under heat and pressure. 1/4 oz boards are great for etch time but the
underlying glass fabric causes visible waves in the transfered toner.
