What I normally do is create a PCB footprint using pads at either end, and
connecting the pads with a track on the mechanical layer.
This means that it will pass the DRC, as the pads are not shorted together.
Just remember to merge the mechanical layer to the layer in question, when
gerbering.

I can answer one of these, the jumper. No idea about the inductor though,
anyone else?
For a jumper there are two solutions, through hole and SMT:
For Through hole, I usually use a shorting link between two holes.
For SMT, you can create a solder jumper in the Schematic in two forms,
Normally Open
and Normally Closed, each with two pins, 1 and 2.
Then create a PCB land patter with two SMT pads, number 1 and 2, place them
very close
together 3-4 thou should do it.
For the NO version that is the end of it, if you ever want to make the link,
simply blob
some solder across the narrow gap.
For the NC version, in the PCB library editor, place a track or rectangle on
the paste mask
layer (normally hidden, you'll need to enable it) across the gap between the
two pads.
This will cause a hole to be produced in the solder paste mask at that
location, allowing
some solder paste to be deposited across the link, making it.
Note, you'll have to allow the narrow gaps for the jumpers within the DRC
rules.
Pity you can't set up a rule template - Yet another enhancement request!!
As for the inductor, would the signal integrity part of the router create an
inductor
if you asked for say 10K Ohm impedance for a track segment? - Any ideas?
Jason.

Hello,
How to create PCB library part with internal connection, ex. normally closed
jumper or inductor imprinted on PCB? DRC gives an error message because you
have two nets connected with copper. Of course, I can connect (short) this
inductor or jumper on schematic but I don t like it. Don t you know some
work around? Thank you, Mike [EMAIL PROTECTED]
