例

VBA:

Sub Example_ArrowHead2Block()
    ' This example creates an aligned dimension object in model space
    ' and then alters the visible appearance (shape) of the arrowhead
    ' using the ArrowHeadBlock property.
    ' Use the ArrowHeadBlock property to set the arrowhead to an existing
    ' block object containing a custom Circle object

    Dim DimPointAngularObj As AcadDim3PointAngular
    Dim AngleVertex(0 To 2) As Double
    Dim FirstPoint(0 To 2) As Double, SecondPoint(0 To 2) As Double
    Dim TextPoint(0 To 2) As Double
    Dim BlockName As String
   
    ' Define the new Dim3PointAngular object
    AngleVertex(0) = 0: AngleVertex(1) = 0: AngleVertex(2) = 0
    FirstPoint(0) = 2: FirstPoint(1) = 2: FirstPoint(2) = 0
    SecondPoint(0) = 1: SecondPoint(1) = 4: SecondPoint(2) = 0
    TextPoint(0) = 6: TextPoint(1) = 6: TextPoint(2) = 0

    ' Create the new Dim3PointAngular object in model space
    Set DimPointAngularObj = ThisDrawing.ModelSpace.AddDim3PointAngular(AngleVertex, FirstPoint, SecondPoint, TextPoint)
    ZoomAll
    
    ' Set arrowhead type to user-defined to allow
    ' the use of a block as the new arrowhead
    'dimObj.ArrowheadType = acArrowUserDefined
    DimPointAngularObj.Arrowhead1Block = "CBlock"
    DimPointAngularObj.Arrowhead2Block = "CBlock"
    ZoomAll
    
    ' Read and display current arrowhead block name
    BlockName = DimPointAngularObj.Arrowhead2Block
    
    MsgBox "The arrowhead block name for this object is: " & BlockName
    
End Sub
