I have a L79L05 from ST Microelectronics, which has the following pinout:
I have created a symbol and package in Eagle for that component. The symbol has three pins - IN, OUT and GND, while the package has 8 pads. When creating device, I connected pads 2, 3, 6 and 7 to the IN pin. As a result, in board editing mode, Eagle adds airwires that asks me to connect all these pins on PCB:
Of course I can overcome these airwires by either ignoring it, or by creating a symbol which has 8 (or 6, as two marked as NC) pins, and assign some of them to a same swap network. But I would like to find a better solution, if there is one.
