I'm very new to EasyEDA and PCB design in general, in fact, this is my first time. So I am sorry if this is a stupid question but I am pulling my hair out over it. The goal of this PCB is to take the 3.3v data signals outputted from a NodeMCU, route them through two Logic Level Converters and pass the new 5v signal to some screw terminals (P7 and P5). I have all of the tracks drawn, there are no DRC errors, but I can't get the top and bottom copper areas to draw. I didn't start with a schematic, I just went straight to laying out the PCB. Attached is a screenshot showing my layout, the copper areas defined, but no copper areas drawn. Is it because I am not using a copper area as a GND plane? Thank you to anybody that takes the time to read this and offer any advice.
