Triangular Sphere 2

[QuicoPRC]

Hi,
well, the reason I've done a truncated icosahedron is because I need to buy a sphere with cells, I think the best option is to construct a truncated icosahedron and then triangulate the hexagons and the pentagons, anyone has an example? have I to project the triangulated points to the sphere? Is posible to divide a sphere to a X equal cells?

too many questions, but it's important.

I have to contruct a 1m diametre Sphere and the cells must be around 100mm

Thank you

there are a lot of ways to do this. You are trying to do this:

You are going to have to use two verticies (nearest neighbors) and the origin center of the icosahedron to create a plane. You will do this twice. You will then use these three points to create a centerpoint arc followed by two lines and you will trun this into a planar surface. You will then create a cirular pattern of 5 instances, and do this again for the other sketch. You will now have ten surfaces and you will then extend three of surfaces and use these surfaces to create split lines on your shpere (the sphere intersects with all the vertices of the icosahedron). Use a copy surface (offset surface of 0) once you created this section and circualar pattern this piece.

You could use this piece in an assembly.

You could also do this with 3d sketch spline on surface, or you could calculate the geometry of these pieces and create them manually.

Not really sure you'll pick this up from my explanation. You can reach me at rfus007 at gmail. I can give you a hand.

My one quetion to you is: Where do you intend to buy a 'sphere with cells' ?

wow, rfus you are the master (several starts coming your way). Nice work.
