Hello. This is my first question in this forum. I made an electronic circuit, and the pcb of  this circuit. I am going to use a CNC for made a circuit in a bakelite plate. How can I edit the pad, I need the diameter of the hole to be 0, and the width and height 10, this is so that the bit drills them as holes. When I want to edit the pad with these data, the program does not accept them Thanks
