Creating accurate sectional curves

Hi All,

I am trying to design a canopy which requires me to work with lots of curves that have curvature in two or more directions. Can anyone tell me how i can fit a curve along these surfaces. In another words I want my top curves to starts bending down from the two endpoints towards where they join together. I believe my images make this more clear.

Hello - one way is to Pull the segments (Explode the blue curve into two) to the surfaces - is that what you mean?

I used the ‘Loose=Yes’ option in Pull to keep the curves’ simple structure.
