gEDA-user: Connect vias to ground plane with no thermal

[Darrell Harmon]

I am currently in the process of designing a single board computer using 
gschem and pcb.  The board will be  4 layer with  ground and power 
planes inside and signals outside.  Since it contains mostly surface 
mount parts with a short trace to the via, I would like to be able to 
directly connect a via to the ground plane.  Does anyone know if this is 
possible?  I have found how to turn off thermals for the entire ground 
plane, but this shorts it to other vias like 3.3V.  I could do this with 
the commercial package I had been using before (Cadsoft  Eagle).

When I get done I plan on putting all of the files on my website under 
the GPL so anyone can build one.  It is based on the Atmel AT91RM9200 
and has 32MB SDRAM, a compact flash socket, 10/100 ethernet, USB, serial 
ports and a FPGA.

Thanks to everyone involved it the gEDA and pcb projects.  This project 
would not have been possible without them.  There is very little I have 
found gEDA and pcb could not do.  Better support for buses in gschem 
would be nice, but that is all I can think of.
