The [nonetlist] patch adds an element flag that makes PCB ignore the marked element when dealing with netlists. This means connecting a net to a pin of a nonetlist element will not cause a short. The refdes of a nonetlist part is drawn with color element-color-nonetlist (ElementColor_nonetlist in the source; default value #777777, grey).
Uses of the nonetlist feature:
This patch introduces a new element flag. The following example demonstrates a 1206 jumper footprint:
Element["nonetlist" "1206 jumper, 0 ohm" "" "1206" 0 0 -3150 -3150 0 100 ""] ( Pad[-5905 -1181 -5905 1181 5118 2000 5718 "1" "1" "square,intconn(1)"] Pad[5905 -1181 5905 1181 5118 2000 5718 "2" "2" "square,intconn(1)"] ElementLine[-2362 -3740 2362 -3740 800] ElementLine[-2362 3740 2362 3740 800] )
This feature is used together with the intconn feature for jumper subcircuits not drawn on the schematics (e.g. 0 ohm resistors).
