Hi, all

I have made a new topic for a long time.

this topic is looks so simple, but I cannot find a way to go.

I made two curves.

Two curves have same x,y coordinates, and different z coordinates.

curve B is on the XY plane.

these two are very similar, but have different length.

(curve A length = 1198609… , curve B length = 1115900…)

and I have made the points on the curve B by segment length.

from now on, I’ll call these points “Length Points”.

obviously, Length Points are on the XY plane.

And then,

I want to find the points on the curve A that has same X,Y coordinates to “Length Points”

…

I am worried that my explanation might be lacking…

but you could understand what I said…
