Quoting myself from the last time it came up, slots can be achieved
via post processing of excellon drill files during/following gerber
export

It can be done with:https://github.com/hackvana/eagle-plated-slots/blob/mas=
ter/eagle-slots.py

which looks for a magic, pre-defined drill size as a trigger to create
a slot joining a pair of consecutive holes of that size where before
there were just two holes in the drill file.

The above script was written by my usual pcb supplier, hackvana, who
hangs out in #hackvana on freenode, i.e. this is a technique supported
by an actual pcb supplier

Looking at the board I pulled this stunt, I had 5 layers with no copper

know I did not
use the hole function.)  I recall placing the traces in each layer, perform
some magic (like MorphPolygon) and done.  No editing gerbers.  No zero
width traces.



Once again, should have noted what I did.



Any other ideas from people?



   Thanks,
