There is a user community for OrCad, but as a previous thread
explained, it is rare to find a layout already made for some package.

The reasons are numerous:

Lots of incompatible CAD programs
Each user has their own requirements of the footprint (things such as
height, keepouts, paste layer etc) that are usually vastly different
across the users.

Implemented layers (and layer names) will vary across users, so unless
you have identically named layers with identical attributes and an
identical number of them, the footprint import won't work anyway.
(OrCad layout isn't particularly 'top of the line' to put it
diplomatically).

The usual answer is 'make your own'

Cheers

Post a reply here with the part number and manufacturer for the IC you
want a footprint for and I will send you a footprint via e-mail.

Best that you learn how to make your own footprints. With the latest
version of Layout, you can use the footprint generator. Easy to make a
footprint in 5 or 10 minutes of any size with the footprint generator.

Layout has lots of parts in their library. Look in the "Quad" library.
They have two versions of a 128-pin QFP.
