I am trying to create some port into model 3D for use into external schematic, because in this mode is more simple use and simulate some external circuit elements. The function of this port is similar a jumper can i open and insert from t point a passive circuit element o other, but the impedance port is 50 ohm(default) and this value affect in the circuit, then is necessary put the impedance at lower infinitesimal value or there is other method to resolver this my necessity?
thanks at all.
