    ' This example creates a text object in model space and
    ' uses the Backward property to flip the text horizontally
   
    Dim textObj As AcadText
    Dim textString As String
    Dim insertionPoint(0 To 2) As Double
    Dim height As Double
    
    ' Define the new Text object
    textString = "Hello, World."
    insertionPoint(0) = 3: insertionPoint(1) = 3: insertionPoint(2) = 0
    height = 0.5
    
    ' Create the Text object in model space
    Set textObj = ThisDrawing.ModelSpace.AddText(textString, insertionPoint, height)
    
    ThisDrawing.Application.ZoomAll
    
    MsgBox "The Text oject is now forward"
    
    textObj.Backward = True
    ThisDrawing.Regen acActiveViewport
    
    MsgBox "The Text object is now backward"
End Sub
