CodeV2

This code is developed to transfer the idea
of taking the iso curves of a surface or dif-
ferent Uv params on the surface and creating a
pattern through piping.
the next stage will involve deformation using point
attractor logic on these tubes.
Code:
Option Explicit

Sub Piping()
'Set Variables
Dim StrSurf
Dim nRows
Dim nColumns
Dim arrParam(1)
Dim arrPointv()
Dim arrPointU()
Dim interpCurve
Dim u,v,i,j
Dim StartRadius,EndRadius

nRows = 75
nColumns = 75
u = Rhino.SurfaceDomain(strSurf, 0)
v = Rhino.SurfaceDomain(strSurf, 1)
If Not IsArray(U) Or Not IsArray(V) Then
Exit Sub
End If
Rhino.EnableRedraw(False)
For i = 0 To nRows
arrParam(0) = U(0) + (((U(1) - U(0)) / nRows) * i)
For j = 0 To nColumns

ReDim Preserve arrpoint(j)
