Techniques for creating paneling surfaces from a closed curve (23.2 KB)

I’m using one closed curve, in order to create a surface to be paneled.
I trimmed the curve using the central symmetry of a circle.
I managed to create one surface from the outline, and the divided circle, but i would like to add more surfaces as show on the picture.

Can someone help me to succeed into this paneling?

Thank you
