How can create branches inside VB Code without using other components

I want to reach a better understand of the branch and Data Tree inside scripting components.
Is it possible to organize the branch of this example inside VB component?
Thanks

Hi Paolo,

sorry for the long silence.

This is actually a bit tricky in the current system, as DataTree(Of T) does not have an in-build Graft method, and Grasshopper.Kernel.Data.GH_Structure(Of T) does not accept data that doesn't implement IGH_Goo.

I'll add a Graft method to DataTree(Of T) for the next release, but here's a solution for the meantime:

Dim ln1 As New DataTree(Of Line)

Dim ln2 As New DataTree(Of Line)

Dim ln3 As New DataTree(Of Line)



For i As Int32 = 0 To Lines1.Count - 1

   ln1.Add(Lines1(i), New GH_Path(i))

Next

For i As Int32 = 0 To Lines2.Count - 1

   ln2.Add(Lines2(i), New GH_Path(i))

Next

For i As Int32 = 0 To Lines3.Count - 1

   ln3.Add(Lines3(i), New GH_Path(i))

Next



A = ln1

B = ln2

C = ln3
