IIRC, the netnames could change if you use one backend or another, due to netname restrictions in some programs... It may be not the best way, but a workaround for this could be the following: - Click on any net in gschem. - Get the components and its pins connected to that net. For example: pin 2 of R1, pin 3 of R2. - Tell pcb or whatever app to select the net connected to pin 2 of R1 and/or pin 3 of R2. This way you handle nets as they are: a connection between pins of components, and you are not tied to any name (it can change when you netlist the schematic). Cheers, Carlos
