Arcs aren't allowed in footprints. You can overlay rectangular pads
along an arc if you need to.
The footprint I use for fiducials is below. The request from the
assembly house was 1mm pad with 3mm clearance. The board that
assembled my last board did not mention any problems (and the

This begs the question, since arcs can be placed on the silk layer in a
footprint, is there a particular reason why PCB couldn't be tweaked to allow
them on copper layers?

D'oh. Neither me nor my copy of PCB knew that so this rectangle with
rounded corners worked fine:
ElementLine [-46000 -12450 46000 -12450 1000]
ElementLine [-46000 12450 46000 12450 1000]
ElementLine
This is in the silkscreen of the footprint.

Hi,
Attached is a fiducial example.
Enjoy!

I am trying to place down some fiducials with a 40mil round copper
center with 88mills of clearance (from the center of the fiducial) and
80 mils of solder mask. I am doing it by using the following command
inside my footprint file.
Pad [-13188 -15000 -13188 -15000 4000 4800
Two notes:
1. Clearance is clearance in polygons, not the line/space rule.
2. Add the nopaste flag to the pad.

Ringing it with copper certainly would work. PCB doesn't have a
generic keep out feature yet.
