I have a component that has two pads per schematic pin.
The component joins these pins when solder so bridging the pads.
In layout the pins are always shown as open circuit if not linked directly with track, which is correct for the layout but would be when
components are added.
Is there a way on the component editor to make these pins joined on the net?
I have in the past just used "ignore errors" |

Hi Andy,
If I think I've understood your question correctly,-
Under Pin Assignments of the Component Editor you can allocate two pins to one schematic terminal,-
ie, under PCB Symbol column, insert 2,4 to connect these two pads on the pcb layout.

Multiple Pin Numbers
As well as assigning pins "one to one", it is also possible to assign multiple PCB pins to a single Schematic pin. This allows you to model certain types of component that have 'internal' connections within the component, or those that have multiple pins that need to be assigned to the same net.
To do this, using the Pin Assignments tab in the Component Editor, edit the pin entry in the PCB Symbol Pad Number cell. The corresponding list of Component Pin Name/Numbers must also be edited to match the PCB Symbol Pad Numbers entered. When editing these for the first time and editing from the default single Pad Number, the Component Pin Name/Number cell will be updated automatically to match. Both lists must have the same number of entries.
Each list can be separated with commas (,) (to assign all the PCB pads to the same net, with connections in the PCB that must to be routed). For example, 1,4,8 When the Optimise option is run, it will show these as unrouted connections. If left unrouted, the Connectivity Check Report will report these as split nets and requiring routing.
Or, separate the pad numbers with plus (+) signs (to assign them to the same net, but indicating that the pins are connected internally within the component and do not all need to be routed). For example, 1+4+8

Andy,
Never tried that .... just try and see !
