[PCB_FORUM] Re: new board

        Another way if you have Concept for your schematic capture is
        to copy the part tables using the exsisting footprints into a
        local part table file, then replace the new jedecs with the old
        jedecs. After running design sync the placement and ref des would
        remain the same and the new footprints would be replaced with the
        old footprints. Silkscreen might need to be fixed. Also if
footprints
        are physically different might cause some DRC's to be fixed.

Sam,
One quick and dirty way would be to extract a placement file from the
pcb, delete the parts from the board, rename the footprints in the
placement file to your names, and then import the placement file back
into the board. One issue to watch for is the rotation that the parts
are built in vs. how they are placed in the board. If after you import
them in you notice rotation issues these can be adjusted in the
placement file and reimported. Like I say this is quick and dirty and
will match the schematic electrically but won't have the same
footprints.

group:

I'm currently doing an eco to an older brd completed by a different
group. We have the same cadence software, and we are using the same
schematic, but we have a different database of footprints. Such as they
have r0603 and we use res0603. I'm assuming this will remove all of
their parts off the pcb. What is the best way to replace their parts
with ours? 
Thanks
Sam
