Generative Grid For laser cutting

Hi all,

I have a flattened pattern grid wireframe unwrapped from a tower. I wish to make them double lined for laser-cutting the structure facade. I do not know how to start by writing a gh to solve the intersection trimming conditions. I do not want to pipe the curves and project the outline as it takes a very long time for the complex grid.

The problem is special as I did not build the grid in meshes which the problem can easily be solved by offsetting the faces. The grid is somehow the intersecting of vertical and radial grid as shown in the attached.
