gEDA-user: manage changes

2009-01-22 Thread Patrick Dupre

Hello,

I previously generated a pcb board. then, I had to make a lot of changes.
So, I copy the previous .sch files into new ones, and created
a new project with the new files. Now, when I generated the new pcb
(gsch2pcb) I lost all the benefits of my previous pcb (I mean, I need
to restart form scratch). How can I generated the new.pcb file
including my changes ? It means the difference between the new pcb
and the old one ?

thank

The refdes and footprint has to match, or else it is thrown out by gsch2pcb.

So you can edit a copy of your pcb to get those matching before running 
gsch2pcb.
Sometimes a text editor is easiest for the footprint part of that, but just use 
pcb to see the topology
that compares to your new schematic and redo the refdes's in pcb.   Save 
versions along the way...
