GetPerpendicularFrames

I'm having trouble accessing Perpendicular Frames derived from a Curve.  I may (or may not) be successfully getting the frames into an array but I certainly can't get them out.  Any ideas?  Perhaps I'm going about this in the wrong way altogether...  Here's the code:

 

Dim myDouble As New List(Of Double)
    myDouble.Add(.5)

    Dim arrPlane As Plane()
    arrPlane = myCrv.GetPerpendicularFrames(myDouble)

    Dim myPlanes As New List (Of Plane)
    myPlanes.Add(arrPlane(0)) 'ERROR IS HERE I THINK!

    A = myPlanes

If you want to add more than one item at a time to a List, you need to use AddRange() instead of Add().

Thanks David.  Unfortunately replacing Add with AddRange only reveals a further problem with my script.  I get the following error:

 

Error: Value of type 'Rhino.Geometry.Plane' cannot be converted to 'System.Collections.Generic.IEnumberable(Of Rhino.Geometry.Plane)'.

 

Any ideas?  Many thanks!
