Arrowhead1Block 示例

使用 VBA 以外的其它编程语言

Sub Example_ArrowHead1Block()
    ' 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 BlockName As String

    Set DimPointAngularObj = ThisDrawing.ModelSpace.AddDim3PointAngular(AngleVertex, FirstPoint, SecondPoint, TextPoint)

    ' the use of a block as the new arrowhead
