Some special components are for PCB only, and have internally connected pads or groups of pads. Two good examples are busbars and SMD jumpers (0 ohm resistors), none of these belong in a schematic.
Is it possible in V14 to interlink e.g. the two pads on a R1206, without going via a schematic terminal?
Problems:
WITH a schematic gate I end up with a pile of jumpers and busbars in the
(corner of) the schematic. Integrety and Connectivity checks works OK.
WITHOUT that gate the schematics is clean, but Integrety sometime fails, and Connectivity
reports lotsa split nets, evident by all the yellow ' threads' criss-crossing the PCB, even though all the nets are fully connected and functional in practice. |

Yes, you can probably assign both pads (of a SM resistor) to be shorted together in Pin Assignments (under Component Editor, i.e. 1+2)
BUT I think you will live to regret it!
Far better to have your jumpers (0R) in the schematic, - just in case! |

No, without a schematic gate & terminal all the assignment menus are grayed |

Try this,-
Create a jumper with both gate and pcb component. Assign both pins as shorted together, place the component on the schematic (with associated nets ), then move the component in the schematic component bin. You'll still get a Design Rule warning, but at least the connectivity should be OK.
PCB connectivity/integrity check should then be OK.

Assign pad to pad in a PCB-only component ?
