Array between 2 curves

I have a drawing like this. I want to array this blue curve. But when I use array curve command, blue line doesnt follow 2 red lines. How can I make this the way I want?

Dear @Aiden_Pearce
you can build a
(1) _loft or maybe a _sweep2
between the 2 red curves (or with the 2 red curves as rails)
(2) _divide the lower curve with the amount of curves you need.
(3) “_extractIsoCurve” to get the curves you’re searching.

if this does not help, please post a .3dm file and sketch the desired result on above screenshot. kind regards -tom

Thanks a lot!
