smoothing blends in NX

[Helmi Bouali]

I was told that a feature that does just this exists in Catia (i can't remember as i haven't used Catia in a long time) but i'll post pictures below to show what kind of result i want (obviously i used trim surface, fill surface and sew again to get this)

is there any such command or a custom configuration in the classic edge blend command that gives similar results?

Thanks in advance!
