Shingle System Script Help

Hi all,

I am attempting to make a “sporadic” shingle system around a surface, I am struggling with creating a curve that follows an option of three points and then creates a close loop. My hope is that I will create a curve along the created surface that follows one number and then I will create a different curve that has a range of the original number and two point rows below and then loft those lines to create layers but I came into a quick stop. If anyone could maybe evaluate the script or give any pointers that would be great. The photo of the chimney is what I am trying create along a bigger surface.
