And you didn’t internalize your geometry; having the .3dm file doesn’t help.

Hi Wong Ping,

Even though your surfaces have varied counts of control points, you can exploit the Deconstruct Brep component to yield the 4 corner points and then build a simple surface from these.

I added additionally logic to unify the surface normals as well.

Hope this helps, cheers!
