The text generation flag specifies if the text is displayed backward or upside-down. To set the text generation flag, use the TextGenerationFlag property. To display the text backward, enter acTextFlagBackward for this property. To display the text upside-down, enter acTextFlagUpsideDown for this property. To display the text both backward and upside-down, add the two constants together by entering acTextFlagBackward+acTextFlagUpsidedown for this property.
This example creates a line of text, then sets it to be displayed backward using the TextGenerationFlag property.
Sub Ch4_ChangingTextGenerationFlag()
Dim textObj As AcadText
Dim textString As String
Dim insertionPoint(0 To 2) As Double
Dim height As Double

textString = "Hello, World."
insertionPoint(0) = 3
insertionPoint(1) = 3
insertionPoint(2) = 0
height = 0.5
Set textObj = ThisDrawing.ModelSpace. _
AddText(textString, insertionPoint, height)
' Change the value of the TextGenerationFlag
textObj.TextGenerationFlag = acTextFlagBackward
textObj.Update
