I haven't figured it out. If I just make a polygon, name it GND, and place one component in it, there is no way to connect one pin to that GND plane. If I make a via, name it GND, there is still no way to make a connection from that pin to that via. I can make another via, name it GND, and a yellow connection will pop up. I still can't connect to those vias. I've made boards with vias to components, but I can't remember how it happened. I think it's only been components which have points that align with grids and a trace is able to snap right to it.
I just don't get it. Why is this program so retarded?
