Did you perhaps mean you changed the geometry instead of topology? Your comment got me wondering if you can change the topology without changing the schematics and I now think you can, as a schematic only defines the electrical connections and the topology is I think also the non electrical relations (what component is next to what). As far as I know topology is strictly dimensionless; size and distance are properties of the geometry. If I were not on HN I would apologise for the pedantry, but here we are

You are right, I should have used geometry.
