So I am struggling with filled zones now.
I am using KiCad 5.1.5 version.
Made a filled zone, selected the Net, layer etc, then right mouse click -> Fill and nothing happens.
Tried switching between Filled Area tools (left tool bar) but it makes no difference at all.
Tried 3D preview with no 3D models of parts and cannot see copper zone at all.
What I have done wrong?
