Hello all. I'm currently using Eagle 6.5.0. I want to put a ground all over my board on one of the inner layers. It will cover my entire board with the exception of one small area. In this area, I want to put another ground that is isolated from the larger ground all around it. They must be on the same layer. I tried drawing another polygon, expecting the existing all-over ground to give clearance, but that's not what happened. No clearance was given. I then drew around the area with a line and clearance was given for that. That doesn't seem like a very clean way to do this. What is the proper way to handle this?
