I'd add a capability of storing net information along with lines, polygons, vias, and other copper objects. It would then make it unnecessary to have the "new lines arcs clear polygons" stuff. A line in a polygon with the same net wouldn't clear. Levente
Hmm... this could be incorporated into
4) DRC re-use: refer to a 'base' DRC rule, rather than re-describing the DRC at every instance. DRC rules could be arbitrarily complex or simple, e.g. elements in DRC class '250V' must have a 0.050" clearance from class '5V', but can have 0.010" clearance within '250V', or something along the lines of the 'skinny, normal, fat, power' we have in place now.A 'net' could be specified by a class/group of elements within which the DRC clearance would be 0 and probably the minimum intersection between two elements would be enforced as the minimum width for that group. If elements are tagged with a net ID, including polygons, then that would still take care of the 'new lines & arcs clear'.
