Help with two way flowing nurb form

Hi
I was hoping to get some input on how I could better create the attached roof. The filled image is using loft between two curves created using grasshopper, however this only works smoothly in one direction, what i am hoping for are nurbs curves flowing in two directions so the bottom of each intersection is a rounded bowl. I’m sure there is a simple method I am missing. Was hoping for some help.

Hi Ash - can you post what you have? I’m not clear about where or if, you want hard corners - do you have an image of the desired shape? In any case, I think I’d do this by making one unit and arraying it, assuming they are all the same.

Hi Pascal
The splines have been attached. No hard corners at all as per the attached image. Thanks
Ash.

HI,

I would model just the highlighted surface(second image), rest is just matchsrf and filletsrf.

Extract just the curves necessary for this block and use interpcrv and match.
