HI, If you need to connect two different nets then that can be done with a zero ohm resistor. This does not mean the pads on the resistor are joined together with a trace. "There Not" , The physical resistor component is performing that shorting function. By way of an example. Suppose you needed to join the following nets. GND and AGND in your circuit then you use a zero ohm resistor. On your board the resistor gets installed which makes the connection. There will be no trace between the two pins. It is a bad idea to use "Net-Short" to fool the pcb to accept a connection between two nets because this will not match the schematic. Golden rule in any design is the PCB Has to match exactly the schematic. The reason is if an engineer looks at the schematic there is the assumption that what he sees on the schematic will be on the PCB. If the PCB is different then you got a time bomb on your hands in particular if an eco is needed later on. I highly recommend you don't use "Net Shorts" in the PCB Editor. Just let the zero ohm resistor perform the function that the schematic is trying to convey instead of shorting pins instead !.
