question about draw a "jump wire" or "fly wire" component.

I want draw some "jump wire" or "fly wire" component for single side PCB.

 

in the symbol,  two pins has same direction,"pas". and  has been names  to "J" and "J@1".

 

but as you can think, it can't has same net on two pin with "pas" direction. so the names of two pins have not effect.

 

it always has a airwire in board editor once you place it on a existing net in schematic editor.

 

does i must set the direction of two pins to "pwr" ? but  it is  unreasonable...

    Hi,

     

    a jumper works like a 0-ohms resistor. You have two pads that are connected to a net each. The name of the pins or pads has not effect on the connections. Don't use Pwr as pin direction. This is not reasonable, as you already wrote.

    Take a look into our jumper.lbr there are some examples you can use.

     

    Regards,

    Richard

    sorry sir.

    I don't want to make a wire like 0-ohms resistor. this will cause a net split to two net.

    and i already look the jumper.lbr, but it is not meet my goal.

     

    insert a jump wire and does not affect original net. that's i want..

    Hello again,

     

    in such a case you have to use two pins that are connected to the same net in the schematic. The name of the pins does not matter. This would result in connected pins in the layout which is represented by airwire between theses pads. IMHO there is no other possibility.

     

    Regards,

    Richard
