GND Zones not filling

I’m trying to fill the GND zones on my PCB and one of the two layers isn’t filling.

The Ortholinear.kicad_pcb file is needed if you want us to have a look at the layout, not the .pro file :wink:

The prj file alone does not help here. We would need the pcb_new file.

A remark on zones: They only fill if something is connected to them. So make sure you have either a via or a pad that connects to the net within the zone. (on the correct layer of course.)

Also look at the clearance and minimum width settings. Maybe these prevent the zone to connect to the pads you expect it to connect to. (Zones have their own settings in their properties dialog.)

All your parts that connect to gnd are on the back side of the pcb. If you place the zone on the back it does fill. But if you place it at any other layer (Front in your case) you need to connect at least one gnd pad to the front by using a via.

(Press v when placing a trace to create a via.)
As soon as you do that the zone fills as expected. Also don’t forget to press b (or start drc) to fill all zones.
