The hole size instruction says if you use a 1mm stroke the hole has to be 1.5mm bigger, because ½ the stroke is inside the circle, but ½ the stroke is 0.5mm, so shouldn’t it be 0.5 + 0.5 = 1mm bigger circle.
PCB view - In Inkscape if I draw a free hand circle of 4.0mm(PCD) with 1.0mm stroke , what size hole will the PCB manufacturer drill it. The circle has PCD(mean dia) - 4.0mm, ID - 3.0mm, OD - 5.0mm -.
I have a 4.0mm hole in the part, but I want 4.2mm in the PCB.
Basically is the drill size the size of the white inside of the drawn circle.
