Hi everyone!
I want to rotate one of 4 faces of rectangle pipe to the normal of the base sphere.
Then remove the intersections of pipes.

Hi Inno,
I attach the surface.
didn’t investigate your definition in deep, but it looks like you’re building rectangular sections on the raw output of Perpendicular Frames planes
I would suggest to align those planes with vectors that point to the very center of the sphere (you are rotating them like 45° later in the definition)

Thank you so much Inno!
That is what i want to rotate.
By the way do you know how to trim away the intersection of the pipes (at the polygon’s corners) in grasshoppper ?
I only looked at your Rhino file and the surface edges of your objects do not coincide. You will have to manipulate the edges before you can trim the ends and join everything into one object. Or start from scratch with clean geometry.
I would create the initial soccer ball geometry based on a truncated icosahedron from Polyhedron plugin which might be preinstalled. If not, it’s available in the package manager.
The beams can be split in a few different ways. A simple way is to create lines from every corner to the face area centroid, extend those lines so they extend beyond the beams cross section, extrude to point and scale from the center.
The result is basically two sets of beams.

No need to install plugins, they are just for preview.

Hi Martin Siegrist,
I had done the dome by following your scripts. Some steps i had to modify manualy in Rihno but it did not take much time.
Thanks a lot !

Thank you, Quan Li !
Such amazing simple scripts, i had saved to my references.
Hi Alls !
I am sorry open this topic again.
I am trying to create the connector between pipes in grasshopper, but i cannot filter the base point to build planes. please help me!

This file contains joined plates at each node and text tags showing the bend angle.
For the extrusions it’s not quite relevant but the plates needed different split planes. Since not all polygons are regular hexagons or pentagons, the polygon center can’t be used and instead the split planes at a corner need to be aligned with incoming / outgoing vectors.
The file can certainly be improved but overall it’s a nice example.
I continued in Rhino 8 WIP and unrolled the bent plates.

What a great support!
You gave me the pole and even the fish
I owe you a lot !
After done finishing steps, i will show the result.
