ULP for fattening tracks to resemble isolation milling?
« on: October 09, 2015, 09:23:08 am »
As discussed elsewhere a common trick to preserve the potency of the etching solution is to make floodfills/ground planes on the pcb even if they are not strictly necessary for the design.   Quite often this ends up with a lot of floating islands (aka orphans) that really should be stitched together - and for a single sided pcb this means extra jumper wires on the top.

Another way of achieving this would be just widening all traces to fill up all available space on the pcb, giving a pcb looking more or less like isolation milling.  This could be done with a lot of polygons roughly shaped like each track and then have different ranks on them to get the isolation. Or having precisely shaped polygons with the isolation already calculated.

Voroni shapes would work as well.

Is there an ULP that does this or something similar?  I know there's plenty of ulps and scripts that makes gcode out of it, but I'd like to have the end result inside Eagle so I can generate gerbers.

Easiest way, use polygons named as the net you want it to be. Just be sure to use the priority function right so the polygons dont overlap

So there's no handy ulp for this - I had to do it manually?
