I'm trying to create a copper fill and send it off for print, but I'm having trouble making the copper fill work. As I understand it's something to do with Net names. I don't have a dc power source. I'm trying to create a hub dynamo usb charger. What is the purpose of Nets and should I fix my naming or maybe there is a work around?
