Note: This property overrides the value of the DIMAPOST system variable for the given dimension.

Examples

VBA:

Sub Example_AltTextSuffix()
   ' This example creates an aligned dimension in model space and
   ' uses AltTextSuffix to allow the user to change the text suffix for the
   ' alternate dimension

    Dim dimObj As AcadDimAligned
    Dim point1(0 To 2) As Double, point2(0 To 2) As Double
    Dim location(0 To 2) As Double
    Dim suffix As String
    
    ' Define the dimension
    point1(0) = 0: point1(1) = 5: point1(2) = 0
    point2(0) = 5: point2(1) = 5: point2(2) = 0
    location(0) = 5: location(1) = 7: location(2) = 0
    
    ' Create an aligned dimension object in model space
    Set dimObj = ThisDrawing.ModelSpace.AddDimAligned(point1, point2, location)
    
    ' Enable alternate unit display
    dimObj.AltUnits = True
    
    ThisDrawing.Application.ZoomAll

    ' Allow the user to change the text suffix for the alternate dimension
    suffix = InputBox("Enter a new text suffix for the alternate dimension", "Alternate Dimension Suffix", ":SUFFIX")
    dimObj.AltTextSuffix = suffix   ' Commit changes to suffix
    
    ThisDrawing.Regen acAllViewports
    
    ' Read back and display the alternate dimension text suffix
    suffix = dimObj.AltTextSuffix
    If suffix <> "" Then
        MsgBox "The suffix of the alternate dimension has been changed to: " & suffix
    Else
        MsgBox "The suffix of the alternate dimension has been removed"
    End If
End Sub
