What am I missing? I want a pad on the bottom layer, with a non plated hole through it. When I put a pad on the bottom layer and them add a hole diameter to the pad properties, the pad them becomes multi layered. If I change the pad properties back to bottom layer, the hole size goes to zero. If I put a pad on the bottom and then put a hole though it. the hole then becomes plated and electrically attached to the bottom pad. I have had two PCB boards made. One has the Pad holes plated, one doesn't. When i look at each PCB layout side by side, the settings appear the same for the pads and holes on both boards. Yet one has plated holes and one doesn't. Any help would be greatly appreciated!
