@User I have been thinking about the DRC Fixing some more and came to the following conclusions: We should add the fixing strategy into the design rules. E.g. "Local interconnect spacing" => "Local interconnect spacing [erase:li]" which says that if there is an Local Interconnect spacing issue, then the DRC fix engine should try to erase the relevant rectangles on the layer "li". This way we can have a generic "drc fix" command which just tries all the annotated fixing strategies on the DRCs found.
