Hallo, first of all: I'm new on CS (evaluating CS as eagle-replacement due to the Autocad-license-model). I'm struggling currently with the DRC/rule-system of CS. clearance between copper and the board-edge: I have copied the board-shape to the keepout-layer and setup a clearance-rule between "all" and "Layer - keepout layer". This gives the desired distance between copper-traces and board edges and works. I need a similar rule to define the distance between copper-traces and unplated drill-holes in the middle of the board. I create these mounting-holes as unplated pads. All copper-traces have a standard clearance of 0,1mm. The minimal distance copper-hole (or copper-milling) is 0,2mm, so the traces are running to close around the hole. (so the pcb-manufacturer rejected my gerber-files) How can I setup such a rule?
