Thanks, Wayne.

Tom,
For my info, what do you mean with "on-line DRC (for less CPU-consuming
checks)" ? (the current on-line DRC is not very CPU time consuming).

I am thinking one other package could be added to Gerber plot generation
+ Gerbview:
This is the "Gerber file function attribute".


see:
www.ucamco.com/files/downloads/file/5/Extending_the_Gerber_Format_with_Attributes.pdf
and:
www.ucamco.com/files/downloads/file/22/Kick_Starting_a_Revolution_IPC-2581_Meets_Gerber.pdf

(Karel Tavernier, the technical manager of Ucamco contacted me some time
ago about this extension).


A pending issue in current Gerber format is the fact you are never
surehow gerber files and stackup are related (mainly for internal layers).

This is an extension to add inside Gerber files
the ".FileFunction file attribute" which identifies the function of the
file.
Add also a "stackup" file descriptor ( see an idea in
Kick_Starting_a_Revolution_IPC-2581_Meets_Gerber.pdf), which could be
read by Gerbview to automatically load gerber files
