u can see my upload image.there is seperation between two faces.it s seen a shaded line.that means in my opinion it shouldnt be seen like that as other faces.
These meshes had a different orientation (different normals) at the gap, that’s why they would shade weirdly there. I added a Unify Mesh component and all works fine now.

Probably not what you’re ultimately after, but I was interested in what all your curves would look like sorted, joined, and lofted.
