Re: gEDA-user: Renumber in PCB/Was/Is List

["Mike Hansen" <mehansen10@xxxxxxxxxxx>]

I was thinking something like this:

-find the part that is closest to the upper left(use the hypoteneuse of the 
X,Y coordinates).  This is our anchor part.   Or we could allow users to 
specify which corner to start at.
-iterate over the list of parts finding the next one closest via hypoteneuse 
from X,Y to X,Y.

Basically the part renumbering would spread out from one corner having the 
lowest numbers to the opposite corner having the highest numbers.
