Create 3D curve from 2D curve

[Shank]

Hi All,
I’m trying to create new 3D curve by move start or end point from old curve.
Any ideas ?

Hello
use Point Deform tool

Hi,
Thank you for your help, but I want the curve look like this.

Hello
you asked

@Shank

by move start or end point from old curve

Under the * there is an expression “x-1”

Thank you. All Good.

And if you input a domain of 1 in the range component you can then use a Graph Mapper at the output in order to go from linear to quite whatever progression of Z.

Thank you, I will try.

Hi, I’m checking by divide curve to many points → move it → Interpolate.
I think curve 1 is more correct than curve 2

I don’t think there is a curve more correct than the other. With control points you don’t decide the interval between them so constant slope is not guaranteed. With divide curve it is more distance based so the increase of height must be a bit more of a constant slope.

Thank you for the detailed explanation.
