What would be needed is a selector to select to which sub layout added objects will belong, default sub layouts would probably be sub sheets. Then they belong to a sub layout they could be selected and moved or replaced with a modified copy. I have made two circuits boards there I copied and reused same layout data the last months. I think a selector to select sub layout would be rather simple to implement although I looked into file format and do not think it is possible to add the necessary information to objects or list of objects without a change of file format. > this track has with = width of another track > this track has constant distance to another track from here to there > width of track = current2width(2A); > track_parameters = impedance2track(50Ohm); To calculate clearance from net maximum voltages and width from net or segment maximum current would be useful. A first step is to get values into pcb and then values or route style could be selected from these values then adding a connection. > Aspö Data > Lilla Aspö 148 > S-742 94 Östhammar > Sweden > +46 173 140 57 Nicklas Karlsson
