"Interp Curves to Surface — Need Help

[deneme]

I want to create surfaces like in the sample image using the curves I obtained with the Interpolate component.
I tried Loft and Ruled Surface, but I couldn’t get a successful result.
Since I am new to Grasshopper, I think I’m failing due to something I haven’t experienced before.

For isocurves like on your picture, rebuild grasshopper curves:
