So,

I tried to use the PCB Jumpers from the standard library, specifically a 
NC jumper. Jumper:SolderJumper-2_P1.3mm_Bridged_RoundedPad1.0x1.5mm  
These seem to be new with the V5 library, because i don't remember them 
with V4.

And it causes DRC errors.  Firstly it generates "Track near Pad" DRC 
errors, because its built from overlapping pads, and specifically the 
middle pad used to create the NC connection is too close to the track 
which terminates on the "Actual" pads.

So i made a local change to eliminate that by reducing the size of the 
"joining" pad.  But that still causes a DRC error "Pad near Pad", which 
is right, because its just a bunch of overlapping pads.  So the question 
is, How is one supposed to use this standard library component without 
generating DRC errors.

I tried a bunch of experiments to create a NC Solder Jumper that doesn't 
create DRC errors and the best workaround seems to be use a NO PCB 
Jumper and manually connect the pins in the schematic like this:

Which works, and doesn't generate DRC errors, because I have to manually 
connect the pads with a fat track, DRC passes.  BUT it is ugly from a 
schematic perspective.

It seems like there needs to be a copper feature of a footprint, that is 
not a PAD (or at least is ignored for PAD DRC checks) to handle cases 
like this.

Don't get me wrong because i think the Solder Jumper components look 
great, but should there be standard components that can't pass DRC?
