I want to create the faceted surfaces shown in the image onto the cylindrical surface next to it. I don’t know Grasshopper very well; how can I do this? I plan to apply the facets to the cylinder and wrap them around it using the “Flow Along Surface” command.

Thanks for your reply, but I couldn’t quite draw it; how can I make the flat surfaces here more distinct?

I tried doing this with a tiered lunchbox, but I couldn’t keep it up

If you want to keep the faces planar I don’t know how to do it.

I am creating surface panels (facets) using Lunchbox, but the surfaces do not remain flat; how can I turn them into flat-surfaced panels?
That is a geometric impossibility. The best you can do is have flat triangles, not quads.
I am trying to work within a triangular arrangement, but things aren’t going the way I want.
I aim to divide the outer surface into clean, flat triangular facets with sharp edges.
My goal is to create the pattern while the pipe is still in its flat (unrolled) state—if possible—and then wrap it around the cylinder using FlowAlongSrf or another suitable method.
I need the triangular pattern to repeat symmetrically around the circumference so that the starting and ending edges join seamlessly when the pipe is closed.
Can anyone suggest a Grasshopper workflow for this?
Go Ali, go go go!
I gotta ask: why are you insisting on flat surfaces?
This does not have flat surfaces:
Neither does this:
What are you doing that require the surfaces to be flat?
You are right. I may have used the term “flat surfaces” incorrectly.
What I do not want is a raised pyramid or diamond relief, where each diamond has a center peak and rises outward from the tube.
What I am trying to achieve is closer to the reference image: a cylindrical tube that keeps its round overall shape, with a repeating triangular faceted pattern following the curvature of the cylinder.
The triangular divisions should create a sharp faceted appearance through edges and changes in surface direction, but without separate raised pyramids or deep protrusions.
So my goal is not a perfectly planar polyhedral tube. I want a round tube with a controlled triangular faceted surface, similar to the reference.
