Newbie question about routing gnd signals.

Community PCB Design

Hello All,

I am looking at the Sparkfun eagle files for the Pro Micro board, and I don’t understand how the ground connections are made. I have highlighted the ground signals in the schematic and I can see the ground pins and several vias, but, as you can see from the picture, they are not routed anywhere. I assume these are routed to a ground plane. How can view this ground plane, and how can I add something like this to my own designs? I have seen tutorials explaining the use of the polygon tool but this board does not seem to have any such copper wells anywhere.

Type “ratsnest;” or hit the ratsnest button, if you can remember what that looks like. When you first load up a board, polygons only show as dotted? outlines. Ratsnest will fill them in.

Damn, you’re right. I can’t believe I didn’t think of that.

Just further explanation, they are created using polygon pours, so the dotted lines are the outline for the pour. Just FYI
