move point on a surface

Hello, I am trying to resolve this issue, I have curve I wanted to project it on a surface, but I want to be able to move a control point to the reflected curve on the surface, but the point should stay on the surface. 

As well, when creating a ruled surface between the curve and created curve form projection on the surface, I am having some weird surface, I want to have a surface that is more continuous and uniform and not with ruled surfaces. 

Any idea please how can resolve the two issues?

Well I want to be able to control one point on the curve, but the curve shall be always in the surface. I made a sketch on how it should look like. the aim is to have a sloped surface between the 2 curves and in other places a linear surface (ike in the drawing the sloped surface is the fushia one)

What I did is the following: 

Copy the planar curve A

modify the copied curve (curve B),the curve B will serve only to the projection) 

Project the curve B into the surface (curve C)

Loft curve A and C.

But the problem is that I am still having ruled surfaces as shown in the picture.

Thank you anyway for your help :)
