Panelling a dome (part from a sphere) with a straight lines

I want to create a rectangular grid, straight lines on a dome, which is originally formed from a sphere, like image-1. I managed to create the grid with contour line commands, but these lines are curves, and I want them straight lines.
I tried to use the lunchbox panelling tool, image-2, but I have had two issues, one is producing the full sphere, even if I import the geometry from rhino. The second issue is that the grid is gradian, not rectangular.
I hope that someone has an idea to achieve this result.

You can check for intersections with the crossing lines, then rebuild from those points as a polyline.

Thank you for your quick reply,

That was what I did, but it did it in a quite complicated way, especially with the data-tree.
Thank you.

So, I can work the same way as the image for the geometry edges, am I right?

Thanks a lot .

Here’s a way to get the perimeter as a polyline (white group). Uses Sort Along Curve with the circle as ‘C’ input:


Nice job @Chuck_Driesler.


Brilliant, thank you
