How to create surface from outline of a bunch of surfaces?

Hello, I have tweened some curves and have a bunch of surfaces by extrusion. I want to get a single surface form outline of these surfaces to apply a space frame structure to the surface. How do I do it.

your outline is the exact thought process you should follow-

on the right and left of your image simply dupedge on those two surfaces (or simply use the curves you used to tween. )

for the top and bottom, you can snap a interpolate curve to points on the end most location using osnaps.

do this to generate a top and bottom curve and then match to connect the ends of all the curves together positionally.

then use edgesrf to create a 4 sided surface
