DRC should be able to get mil units right. It's mm that you might
want to bump up a little.

Are you saying that 0.000254 mm should be added to your DRC rule if
exporting to gerber? (ie, a 4mil DRC would become 4.01mil)

Thanks for your work on this Andrew, it is a much anticipated improvement :)

Related to my prior post - I tried to build gerbv 2.5.0 on Fedora 15,

Hello,
I recently completed a rather intricate PCB with 0.8 mm pitch BGA's.
When I sent it off to a manufacturer (Eurocircuits), a ping-pong game
developed, with my design being rejected several times because it didn't
conform to the design rules for a regular production pool(*).
Now I found tha
Hi Bob,
according to the archives, you were looking in August 2006 for
manufacturers of PCB on ceramic substate.
Did you find anything?
I'm looking for something similar now, for a circuit containing a
few Hittite HMC975 switches (it's not cryogenic, however).
Another problem I have is
