I created a surface,
on this I have created a rectangular hole to remove drafts and replenish the surface,
I realized the surfaces by imposing tangence in all 4 directions,
I tried to merge the created surfaces but catia returns the attached error: why?
gives you that kind of error when there is no connection between the surfaces.
you can try to increase the closing margin (merging distance) up to 0.1.
sure without seeing the surfaces is not easy to help you.
