redrawing a gaudi's structure, problem with selection of points...

Hi all, I'm redrawing the structure developed by Gaudi to build some of their chimneys, and I'm stuck in the selection of points to be joined through lines and generate warped surfaces.

Chimeneagaudi.gh
one may give me some idea of how to get this string of points?

The final image shows the points to be selected to form the surfaces ...

grateful
