Hi Guys,
For some reason I having hard time to make hex pattern on spherical surface.
I want to apply hex pattern on a surface, make it planar and then extrude.
See attached image of what I want to get at the end.
Thank you

Instead of using Lunchbox, this is another way using weaverbird dual graph for initial hexagon pattern setting on your surface.
Thank you Kim, I will take a look.
And I donât think the hexagons from your reference image are planar⌠Are you sure about that?
@HS_Kim the reference image used here in this thread was by @arthur tedeschi in his Instagram and grasshopper blog he explained that as a planar hexagon.Arthur Tedeschi hexagon
He refers that he used kangroo + grasshopper to achieve this. Thank you 
Yes. on a properly shaped surface, Itâs sometimes successful, but itâs not easy to maintain the shape of the hexagon, especially for concave parts. Check the linked topic bellow.
Hi Tim,
Is there a way to remove pattern after I have trimmed the surface ?
Yes, I was looking on different sources to find a solution before posting here. And I found an example at old grasshopper forum.
I am getting closer, but I still getting messy edge. How would you make it follow actual trimmed form?

If you could allow more deformations of hexagons, youâll probably get more chances to generate planar panels during your K2 simulation.
Youâll need ngon plugin.
Iâm Kim.
Sorry 
So you are saying I just need to wait a bit longer ? I do want he[agon to be stretched to the edge without triangular infills.
Cheers
What are you waiting for? Would not it be possible to modify existing one?
Btw ICD/ITKE pavilions use mostly TPI for discretization. One of many papers:
And just for information the most recent wood pavillion at BUGA opened on last Wednesday:
Very interesting, thank you.
I think you are correct. It looks like ngon is what I want. But it looks like I will have to rebuild a shape first in Rhino so it is not a trimmed surface to be able to apple pattern on it. NGON doesnât apply patterns on closed surfaces like sphere !? Or am I missing something?
Your result is almost what I need, but without left over triangular gaps. I am trying to fill it with hexagons. So hexagons on the edge a stretched to fill in the left over space.
Cheers

Hi guys, sorry for my late reply. As soon as possible Iâll publish the definition, Iâm currently testing it on mixed GC surfaces and it is very promising :))
Andrea is right, it is not a TPI process but is a âcustomâ algorithm which uses the âplanarâ component by Daniel.
best,
Arturo
You can see the definition at the end of this blog post. It has a simple Kangaroo 2 to planarize hexagons on a surface. You can download the GH definition and the Rhino file at the top of the post.

@HS_Kim Gday Kim, was wondering if you could take a look at my post, Iâm doing a very similar thing with planarising my surface, however it is not so successful. Cheers Extruded hexagon panels on surface with different scaled openings
I can´t really figure out how this logic works 
but could be applied in an open surface?
