Hi, I am trying to create below pattern in Grasshopper3d but I am struggling. Could anybody please help me out or show me few tricks. I have attached my Grasshopper file.

This is one way to approach diagonal rafters, though it would be better to intersect sightly rotated planes with a cylinder to get the proper shape.

Something like this (extruded arc), though as you can see, there are details to get right.

One of many details I was referring to is that as rotation angle is increased, plane intersections are missing on part of the roof, as you can see at the bottom of this image:
So I added a purple group to extend the edge line, increase the number of planes (without affecting distance between them), and move them.

This is still far from fully “automagic”, as parameters require micro adjustments to get everything to look right, but it’s a step in the right direction, eh?
Cut the mirrored (colored) rafters to let the unmirrored rafters pass through.
P.S. Later - eliminate one slider, re-use ‘Height’ slider instead.
