Hi Daniel,

 

if your input parameters need to behave as list parameters, you need to change both RegisterInputParams() and the Da.GetData() calls. Basically when you get lists from the input then the data iteration is very different, so Grasshopper needs to know in advance if you're planning on doing this.

 

Protected Overrides Sub RegisterInputParams~

  pManager.Register_DoubleParam("double","d","double", GH_ParamAccess.list)

  pManager.Register_PointParam("point","P","point3d", GH_ParamAccess.list)

End Sub

 

then

 

  Dim dbl As New List(Of Double)

  Dim ptl As New List(Of Point3d)

  If (Not DA.GetDataList(0, dbl)) Then Return

  If (Not DA.GetDataList(1, ptl)) Then Return

Dear, David

Thank you very much,,..

Input Paramater works well.

 

But, OutPut parameter was different.

Protected Overrrides Sub Register OutPutParams~>>>

pManager.Register_DoubleParam("double","d","double", ""not possible to write here"")

pManager.Register_PointParam("point","P","point3d", ""not possible to write here"")

Is there any more to modify?

I can retrofit the data layout of outputs, so there's no need to set the access type. All you have to do is either call

 

DA.SetData()

 

or

 

DA.SetDataList()

 

depending on what you want to output.
