Mark,
You may have already considered, but thought I'd suggest anyways .
Much better to use pours connected to GND than thieving if you can get
reasonable connection - eliminates worries about possible electrical
problems created by the thieving patterns.

It looks like this will be a very useful utility. One more question: Can
anybody tell me if it is better to have copper balance pads aligned or offet
from layer to layer?

Is there a list of all Allegro commands available?
Yes, Tools->Utilities->Keyboard Commands.

Uri,
Thanks a lot!
I could not find anything in Allegro Help.
It looks to be exactly what we were looking for.
Is there a list of all Allegro commands available?
There is an Automatic Copper Balance PDF on Source Link, but looks like
a skill file that would have to be loaded independently.
We will give your suggestion a try Uri.
Thanks again,
Mark

Does anybody know of an easy way to create (in Allegro) copper balance
thieving dots?
We are instructed to balance all boards in the database and not to give
fab free rein in their placement.
We are currently adding 100 mil shapes on 200 mil spacing...manually.
Thanks,
Mark
