Hi AlanChen. So in order to get my silkscreen design to cover the vias I've exported a version of the gerbers where I've deleted the vias in question and then copied the silkTop.gbo and the silkBottom.gbo into my main gerber export folder replacing the silkTop.gbo and the silkBottom.gbo that where there.
Will this work as I expect it to? Or do I need to do the same for the maskTop.gts and maskBottom.gbs files?
