[PCB_FORUM] Replacing ripped up etch?

Hi Everyone,
Hopefully this one is as easy to solve as the last question I posted. :-) 

We have a board file that was converted from pads but has an orcad sch. We
are now synching the converted brd file with the sch. We had to remove a
bunch of pins from some bgas that were okay in pads but we didn't want in
allegro. I have loaded the netlist and replaced the few symbols that
wouldn't place, or refresh, automatically (due to the "missing pins") but
now I have a bunch of routes that have become rats. These appear to be ones
that went from the offending symbols to other offending symbols so its not
all rats for these refdes but only a few per refdes with multiple refdes
involved. I have tried everything I can think of in every combination I can
think of to no avail. So the million dollar question is: Is there a way to
get those routes back without having to go through by hand and make a clip
file? Something similar to a placement file but for routes, maybe?
Thanks in advance,
Dharma
