that Pad Class and Polygons.

Subject: [PEDA] fiducials

I have been trying to create fiducials on my design (both local and
global)
I have been creating them by creating a pad, on the top layer:
diameter = 1mm
hole size = 0mil
solder mask expansion = .5mm
paste mask expeansion = -1mm

This creates a nice  fiducial,  but the polygon ground plane get too
close to it (using the default cleance rules).  If I use the keepout
layer, I can route on any of the layers. 

Any suggestions would be  appreciated.
