Hello! i am new to grasshopper and would really need some help. I have to prepare a cast out of styrofoam to pour clay into but don’t know how to generate this pattern. I would really appreciate an answer, thanks in advance! 
Well, mentioned T-Splines is a plugin no longer available. You might want to try Weaverbird plugin…
- Create an extrusion (a cylinder) or some other thing (loft var radii circles for instance).
- Spread rnd points on the Surface and use a BallPivot algo to get a mesh.
- Or - rather better - use MeshMachine and vary the L in order to control the size of the mesh faces,
- Get the mesh edges.
- Gonnect some vertices to the central spine (find the prox points). Add the lines to 4. Or use rnd pts on some edges and do the same.
- Sort (Z) the spine prox points make a Poly and add the Poly segments to 5.
- Having a Line Graph on hand try to "“thicken” it either via pipe on TSplines or use stuff the likes of ExoW, Dendro or IntraLattice. Me? TSplines by a huge margin (but they are dead by now - a huge AutoDesk mistake).
Forgot to mention the prox way (the central spine is not used: a bit kitsch).

Used a TSpline pipe component … but the best way by far is to bake the line graph and do the TSpline marvel by varying manually the R/T values.

Forgot that prox does trees with duplicate elements (and thus the TSpilne pipe had a very hard time). Used a thing from Kangaroo1 in order to remove them (or you can use Topologizer for that).
Use this (added TopoW and WB CC). That said TopoW is a bit temperamental … but if it works nothing comes close.

Man, what I can say? Hackers everywhere, it seems. But how they did that? You tell me
Added Intralattice and a small thingy in case that you don’t have Kangaroo (or Topologizer) for removing duplicate lines out of the Prox (NOTE: it’s not a bug, it just yields results having connectivity matters in mind).
