I have a question about fill areas. I have noticed that if I want to have a fill area over an entire board, such as a ground plane, I can place a polygon around the board and name it something like "EarthG" and it works fine. The fill will surround the pads and traces properly. However, If I have any other filled areas on the board like just around a few pads, the fill area for the ground goes directly over the other fills without any regards to being different names. Why? The only way I've found to avoid this is to manually use traces to fill in the areas I want filled in and then the larger surrounding fill will avoid those areas.
