To create extra pins for component, after adding pins on PCB, select each one: Right Click on the pad, highlight 'Pad ...', select Edit Pad from submenu, change Net name. This will not be shown on the schematic and may need to be redone if netlist changes. If you want these extra wholes on the schematic, you need to create 1 pin connectors, test points or something else to transfer them to the netlist. If you have multiple components with the same 'extended' footprint, I would create a new component in your library which would be the easiest. Martin
