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'
