Figure 1 is the effect I want, Figure 2 is the result I got.

How you got the result in the figure 1?

Hi Z,
Do the curves have the same direction? Now I don’t have access to RH&GR to check your file.

I think this what you are after:

Because of the overlapping lines between the surface and the surface of the surface, what should I do to select the curve I want?

I made a mistake last time. Actually, I want to change its cross section, not the same.

What are the steps you took to deform the surface like that? I guess you did that in Rhino, not in Grasshopper. You can use subselect for the edges that will be the centerline for the pipes.

In grasshopper: select the deformed surface > deconstruct brep > select the edges you want (based on the length: see the last grasshopper file) > use pipe (or sweep circles, along the selected edges.

Not at a computer right now.
