Thanks again. Actually the ground plane was created in paint shop pro.
I just created a negative image. Made a selection set with magic wand
then used the command selection-modify-contract to place a copper
removed trace around the circuit. Then just made the ground trace
copper removed area black.

Regards
Dennis Waggoner
