Hi Matt,

I assume this is a scripting exercise for its own sake? It can be done using standard components.

Finding the highest and lowest values in a list is something I usually solve as follows:

Dim min As Double = Double.MaxValue

Dim max As Double = Double.MinValue

Dim minIndex As Int32 = -1

Dim maxIndex As Int32 = -1

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

  Dim z As Double = points(i).Z

  If (z < min) Then

    min = z

    minIndex = i

  End If

  If (z > max) Then

    max = z

    maxIndex = i

  End If

Next

Yes, it is an exercise for the sake of scripting.  I have done this with components (many many times) which is part of the reason I want to script it.

 

I would also be interested in developing domains and ranges, but I cannot find the namespace which houses these classes.  Primarily, I would like the ability to grab values from a list, and also to develop values based on ranges.

 

Thank you for the examples.

 

Regards,

Matt

If you want to create a domain or interval, you can use either Rhino.Geometry.Interval or Grasshopper.Kernel.Types.GH_Interval. The GH_Interval merely wraps around the rhinocommon interval and makes sure that IGH_Goo is implemented. If you provide a Rhino.Geometry.Interval then Grasshopper will wrap it into a GH_Interval for you.

So at the end of the code above, you could add:

A = New Interval(min, max)

I will try this on the way home tonight.  Thanks David.
