vb : how to change 1-dimensional array list to normal list?

Hi, i have a question.

I make a logic that makes edge curves in triangle surface.

this return output is that.

{0,0,0} - (3)

{0,0,1} - (3)

{0,0,2} - (3)

{0,0,3} - (3)

{0,0,4} - (3)

{0,0,5} - (3)

{0,0,6} - (3)

total output is 7-branch, and each branch have three edge curves.

but I make this output to one branch list like grasshopper component 'flatten'

21 locally define values

line-like curve

how to make this?

runscript(byval trisurfaces as brep, byref a as object)

dim explodecurves as curve()

explodecurves = trisurfaces.duplicateEdgeCurves

dim curvelist as new list(of curve)

for each explodecurve as curve in explodecurves

curvelist.add(explodecurve)

a = curvelist

thanks

You can't. If you want to output a single list of data, you must do so within a single iteration of the RunScript method. You can change your trisurfaces input to list access:

RunScript(ByVal trisurfaces As List(Of Brep), ByRef a As Object)

Dim explodeCurves As New List(Of Curve)

For Each brep As Brep in trisurfaces

explodeCurves.AddRange(brep.DuplicateEdgeCurves())

Next

a = explodeCurves

End Sub

wow thanks! your method is working well!

but, i have a question. what is different single list and list access?

they seems similar...

If you set the input to List access instead of Item access, the RunScript signature changes from:

RunScript(ByVal trisurfaces As Brep, ByRef a As Object)

to:

RunScript(ByVal trisurfaces As List(Of Brep), ByRef a As Object)

This allows you to iterate over all the Breps that 'belong together' and aggregate the results into a single list. I'm not sure what it is you're asking though, so this may not be the droids you're looking for.
