Problem creating skeleton

Hii im still into the basics of ghp and I was trying to build an exoskeleton for a tower im making, the problem is I cant get the points to follow the path I have in mind, that I actually have no idea on how can I achieve it, something like the picture, and I was wondering if someone could help get the logic please?Thanks!:slight_smile:
