Update Model from Database not picking up Relationships

I just started using Toad. I’m trying to update my model by getting new objects from a database. It’s not picking up the relationships (FK constraints) defined in the db. Any option/setting I’m missing here? I’ve looked at all possible settings and I’m still having the same problem.

Also tried to reverse engineer a db. It didn’t pick all the FKs either.


I already faced this issue but still not able to find solution. When you get solution please let me know.
