Newbie level 4
I need to define areas where nothing will be placed, including polygon pours, but which don't get routed. The keepout layer works perfectly on the screen, but the manufacturer will rout big holes in my boards. I thought I could do it with a mech layer, but I can't define clearance rules for other layers. I can define poly cutouts, but it's clunky, doesn't prevent tracks, and I can't make circles. Anyone got a fix?
