I've done this before so I know its possible, but I can't seem to get it to work this time. I've made a circular PCB defined by a circle. I click the circle and then choose "Create Polygon from selected primitives". Then I go to polygon manager (first attached image) and change it Solid copper fill. Finally I hit repour ... and nothing happens. I just get a transparent polygon over my layer (second attached image).
What am I missing?
