例子

VBA：

Sub Example_TextPosition()
    ' This example creates an aligned dimension and then changes the
    ' TextPosition property for that dimension.
    
    Dim dimObj As AcadDimAligned
    Dim point1(0 To 2) As Double
    Dim point2(0 To 2) As Double
    Dim location(0 To 2) As Double
    
    ' Define the dimension
    point1(0) = 5#: point1(1) = 3#: point1(2) = 0#
    point2(0) = 10#: point2(1) = 3#: point2(2) = 0#
    location(0) = 7.5: location(1) = 5#: location(2) = 0#
    
    ' Create an aligned dimension object in model space
    Set dimObj = ThisDrawing.ModelSpace.AddDimAligned(point1, point2, location)
    ZoomAll
    MsgBox "The current text position for the dimension is " & dimObj.TextPosition(0) & ", " & dimObj.TextPosition(1) & ", " & dimObj.TextPosition(2), vbInformation, "TextPosition Example"
    
    ' Change the text position location
    location(0) = 8.5: location(1) = 7: location(2) = 0
    dimObj.TextPosition = location
    dimObj.Update
    
    ' Return the endpoint of the first extension line
    ' Note that the return value is a Variant
    Dim retPoint As Variant
    retPoint = dimObj.TextPosition
    
    MsgBox "The new text position for the dimension is " & dimObj.TextPosition(0) & ", " & dimObj.TextPosition(1) & ", " & dimObj.TextPosition(2), vbInformation, "TextPosition Example"
End Sub
