Curves to fins

Hi guys,

I’m looking to achieve a certain type of ‘FINS’ or ‘LOUVRE’ type effect from the tweened curves from puffer fish.

My plan is to extrude each curve along the rail of the tween and then extrude the resultant surface to its perpendicular.

I need help on how I can do this

Thank you.

maybe something like this?

Thank you. I will have to check it out. This seems to works great but also I need to extrude those fins again to have a thickness.
