例子

VBA：

Sub Example_MTextAttribute()
    ' This example creates an attribute definition in model space.
    ' It then manipulates its MText properties
    
    Dim attributeObj As IAcadAttribute
    Dim height As Double
    Dim mode As Long
    Dim prompt As String
    Dim insertionPoint(0 To 2) As Double
    Dim tag As String
    Dim value As String
    
    ' Define the attribute definition
    height = 1.4
    mode = acAttributeModeVerify
    prompt = "New Prompt"
    insertionPoint(0) = 5.2: insertionPoint(1) = 5.7: insertionPoint(2) = 0
    tag = "NEW_TAG"
    value = "New Value"
    
    ' Create the attribute definition object in model space
    Set attributeObj = ThisDrawing.ModelSpace.AddAttribute(height, mode, prompt, insertionPoint, tag, value)
    
    attributeObj.MTextAttribute = True
    attributeObj.MTextAttributeContent = "test content"
    attributeObj.MTextBoundaryWidth = 4.2
    attributeObj.UpdateMTextAttribute
    ZoomAll

End Sub
