I am very new to Kicad. I am busy with a project with 3 board. the 2 small boards worked well with filling. the larger board does not fill. I have read a lot and tried several options to get this working without any success. I am sure it is something i did or not doing that is causing this. I am just not sure where to look.
Welcome to this friendly forum!
First reply after the lot of 21h means, that you provided not enough information.
A screenshot, the project itself, further explanation would help to help!
