Convert your pads to square, set your routing up to
90degree only, and you should get pretty close, but
you may have to tweak trace widths.
Then create a unconnected ground net, lets call it
ugnd If your software doesn't like it, you can use a
1206 resistor to connect the ugnd to gnd, if it needs
to pass DRC, then just don't populate the 1206.
Next pour a poylgon plane with a clearance section
equal to your cutter's diaemeter and connect such
polygon plane to ugnd. Also be sure to set your
software up for leaving dead copper fills. It was a
common technique used up until around 1984 or 85, when
EMC became a regulatory issue.
