Because the question frequently arises of how to connect two or more
grounds while maintain DRC and the separation of the grounds except at a
single point, and because the instructions as to how to do this can be
misinterpreted, I have uploaded to the protel-user filespace a PCB file
with two virtual short footprints in it, two grounds which are shorted by
the footprints, and a Design Rule which allows the close proximity which is
the key to this method. The gap is 2 microinches and the design rule allows
1 microinch for that footprint.
The file is in the filespace at
http://groups.yahoo.com/group/protel-users/files/
and the direct URL for file download is
