Hi,
I've been trying to get a grip on how EaglePCB handles inner layer ground planes. It appears that they have something called a supply layer to do this. From what I understand, given that your ground net is called "GND":-
1. Create a new layer. (This usually goes to 103, I can't get any lower.)
2. Name the layer "$GND".
3. This will automatically display as "GND".
4. This will now automatically serve as an inner layer.
5. Anything you draw on this layer actually removes copper instead of adding it.
In other words, you don't have to draw anything on this layer, except perhaps a border to keep the ground plane clear of the edges.
Well I've done all this but for some reason, the GERBER files that the CAM processor generates for this layer is empty. Am I missing something here? Any help will be greatly appreciated.
Regards,
Daniel
