In another thread, I ended up with “dirty polylines” that double back on themselves with overlapping segments. I tried various ways to find the pair of points (in a cloud of segment end points) most distant from each other and stumbled on Discontinuity for that job, though am not quite sure why it …

It should work in any version of Rhino.

[image] anon39580149: Try with fit line Fit Line works well with the ‘Sphere Lines’ because their discontinuity points are distinctly linear. The ‘Random Grid’ is more problematic because the rectangular curves must be broken up and sifted into horizontal and vertical segments before joining…

I am not sure if i understand the problem, for grid you can also use fit line. [image]

Thanks anyway but I don’t recreate code from images, especially icons. And as I explained in my previous post, I tried using Fit Line and didn’t find it useful for the random grid of rectangles.

Here’s one way:

needs this component:

Line merging algorithm

Is there a faster way to make a seamless morph on a round surface
