Faced the problem of cutting out internal holes. In easyEDA, everything is fine and shows (see fig. 1). But when switching to JLCPCB (see fig. 2) or GerberViewer (see fig. 3), this area becomes just a board border, not a cutout and accordingly is simply ignored in JLCPCB (it leaves textolite there). Is there a solution to this problem so that you can make arbitrary cutouts on the board and then they are normally recognized in JLCPCB? pic.1  pic.2  pic.3
