How to get/set the 2nd dimension text? (in SW 2015 SP2.1)

Hello,

I'm not sure if "2nd dimension text" is the correct term, I mean "75h7" in this picture (red marked):

I tried to use the GetText method but it seems that I can access only the 1st dimension text:

Sub Test()
  Dim swApp As SldWorks.SldWorks
  Dim swFeat As SldWorks.Feature
  Dim swDispDim As SldWorks.DisplayDimension
  Dim swDim As SldWorks.Dimension
  Dim i As Long

  Set swApp = Application.SldWorks
  Set swModel = swApp.ActiveDoc
  Set swFeat = swModel.GetActiveSketch2
 
  Set swDispDim = swFeat.GetFirstDisplayDimension
  Do While Not swDispDim Is Nothing
    Set swDim = swDispDim.GetDimension
    Debug.Print swDim.FullName
    For i = 0 To 8
      Debug.Print i, swDispDim.GetText(i)
    Next
    'swDispDim.SetText x, "Whatever"
    Set swDispDim = swFeat.GetNextDisplayDimension(swDispDim)
  Loop
End Sub

Any ideas?

Andreas.
