Example
VB 
' Find a 3D view type
Dim collector1 As New FilteredElementCollector(document)
collector1 = collector1.OfClass(GetType(ViewFamilyType))
Dim viewFamilyTypes As IEnumerable(Of ViewFamilyType)

viewFamilyTypes = From elem In collector1 _
                  Let vftype = TryCast(elem, ViewFamilyType) _
                  Where vftype.ViewFamily = ViewFamily.ThreeDimensional _
                  Select vftype
' Create a new Perspective View3D
Dim view3D__1 As View3D = View3D.CreatePerspective(document, viewFamilyTypes.First().Id)
If view3D__1 IsNot Nothing Then
    ' By default, the 3D view uses a default orientation.
    ' Change the orientation by creating and setting a ViewOrientation3D 
    Dim eye As New XYZ(0, -100, 10)
    Dim up As New XYZ(0, 0, 1)
    Dim forward As New XYZ(0, 1, 0)
    view3D__1.SetOrientation(New ViewOrientation3D(eye, up, forward))

    ' turn off the far clip plane with standard parameter API
    Dim farClip As Parameter = view3D__1.LookupParameter("Far Clip Active")
    farClip.[Set](0)
End If
