例子

VBA：

Sub Example_DrawingDirection()
    ' This example changes the drawing direction for an MText object
    ' in model space.
    
    Dim MTextObj As AcadMText
    Dim corner1(0 To 2) As Double
    Dim width As Double
    Dim text As String
    
    ' Define the MText object
    corner1(0) = 0#: corner1(1) = 6#: corner1(2) = 0#
    width = 7
    text = "This is a text String."

    ' Create the MText object in model space
    Set MTextObj = ThisDrawing.ModelSpace.AddMText(corner1, width, text)
    ZoomAll
    
    'Change the drawing direction of the MText object
    MTextObj.DrawingDirection = acLeftToRight
    ZoomAll
    MsgBox "The DrawingDirection of the text is left to right.", vbInformation, "DrawingDirection Example"
        
    MTextObj.DrawingDirection = acTopToBottom
    ZoomAll
    MsgBox "The DrawingDirection of the text is top to bottom.", vbInformation, "DrawingDirection Example"
        
    ' Return the drawing direction
    Dim retDirection As Integer
    retDirection = MTextObj.DrawingDirection
    
End Sub
