Very simple but exact surface from curves

How would you use the attached curves to build the attached surface?
Goal: simple and fast.

The surface attached is built from a sphere, but that method is to heavy for our experiment.
Sweep doesn’t work and rail revolution requires cutting afterwards which is also to heavy…
And patch is of course far too inexact.

Any ideas? (15.1 KB)

Here is one way.

Hi Dowazura,

thank you for your reply and the very beautiful setup.

Actually, I already tried a solution like yours (only minor differences).
It’s the cutting procedure that makes everything slow.
I want to map it huge! With curves, that would work fine.
I am beginning to think it is impossible without cutting.
