Path planning in Catia

Hello,
I'm new here, and I'm a student. I'm working on a project at College to make paths on CAD models in Catia.
I came across a problem.
I choose a surface and mesh it to get points on surface. When I export those points to txt and excel files they are in random. And when I go through macro to make spline from that points it's just some random spline, not in any order. So my question is, is there any macro or any other way to rearrange those points in some order to make nice splines.

Pictures of how it should be (I did that via choosing points) and how it is via macro are in attechments.
