gEDA-user: gerbv undefined apertures warning




In viewing the gerbv warning for a small set of gbr's (made with PCB) I'm getting a an "Undefined aperture number called out in D code" warning message.

I can narrow it down to no-plate mounting hole. While I assumed it was the no-plate that caused the blip, it's actually something with the copper or clearance:

Element[0x0 "MTG__keystone-612_4-40-L-bracket.fp" "M?" "" 0 0 -10000 8500 0 100 0x0]
(
	Pin[0 0 11500 11800 35000 12500 "" "1" 0x08]
	ElementLine[-12500 18750 -12500 -12500 1000]
	ElementLine[-12500 -12500 12500 -12500 1000]
	ElementLine[12500 18750 12500 -12500 1000]
	ElementArc[0 0 17500 17500 0 360 1000]
)
...

Pin flags = 0x01 also causes the same warning in GERBV.

This brings up the question of what happens to copper that is set to 0 thickness or thickness smaller than the hole (with the intent of making it not print to the gbrs).

in other words, what's the right way to specify holes with no copper if it isn't the above?
