다층에서 폴리리전과 패드 사이의 클리어런스 제약

Solution Details

This error usually occurs when you do not have any stackup assigned to the board. You can go to board planning mode (by pressing the "1" key), then right-click on a board region to choose Properties from the context menu which will bring up the Board Region dialog so that you can assign the stack up to the board region.
