How to Loft Curves Interpolated from Irregular Grid?

I’m trying to create a topography-like surface using curve attraction. I created a grid, pulled points for attraction, and then interpolated the points to create curves. However, I can’t seem to loft the curves to make a surface. How do I proceed or is there a better way? ThanksCurve Attraction to create (13.6 KB)

Have you checked baking the interpolated curves to Rhino and lofting them?

Also check the curves are a flattened list, in a sensible order and have the same direction.
