If I use a circle to make a top silkscreen figure for an LED, put it on the “Top Placement” layer, and DO NOT select “Area: _ Filled”, I get a filled circle when exporting to Gerber. Other data: the circle’s line width is 0.4mm and the circle diameter 5.2mm. Several Gerber viewers were used to check this.
The expected behavior is to output a donut with an unfilled hole unless I select filled. Without this functionality, I cannot create a conventional LED silkscreen image on the board.
I am on MacOS Catalina 10.15.7 and LibrePCB 0.1.5.
