Loop - Recall Feature Points from Pattern of Curves

[[Ri...]]

Does anyone know of an efficient way to Recall Feature Points from a Curve that has a Pattern on it? In my example, I have a group of (4) curves that has a 116x pattern on them. I need to then create a FreeForm Surface for each 4x group of curves - so essentially I need to create 116x FFS that pulls from the correct set of (4) curves. 

Any and all help is greatly appreciated.

Hello Richard,

I didn't fully understand what you're trying to achieve. Could you post a few pictures of your current setup and what you're aiming for?
