2024-5-18 19:21| 发布者: admin| 查看: 121| 评论: 0|原作者: admin|来自: AutoCAD

指定第二条扩展线的终结点。

支持的平台：仅限 Windows

签名

VBA：

object.ExtLine2EndPoint

对象

类型：Dim3PointAngular、DimAngular

此属性应用于的对象。

属性值

只读：不

类型：变体（双打的三元素阵列）

表示第二条延伸线的端点的 3D 坐标。

言论

和属性包含扩展线的端点。如果给定维度不存在延伸线，则这些点将等于和。ExtLine1EndPointExtLine2EndPointExtLine1StartPointExtLine2StartPoint

例子

VBA：

Sub Example_ExtLine2EndPoint()
    ' This example creates an angular dimension. It then changes
    ' the location of the ExtLine2EndPoint.
    
    Dim dimObj As AcadDimAngular
    Dim angVert(0 To 2) As Double
    Dim FirstPoint(0 To 2) As Double
    Dim SecondPoint(0 To 2) As Double
    Dim TextPoint(0 To 2) As Double
    
    ' Define the dimension
    angVert(0) = 0#: angVert(1) = 5#: angVert(2) = 0#
    FirstPoint(0) = 1#: FirstPoint(1) = 7#: FirstPoint(2) = 0#
    SecondPoint(0) = 1#: SecondPoint(1) = 3#: SecondPoint(2) = 0#
    TextPoint(0) = 3#: TextPoint(1) = 5#: TextPoint(2) = 0#
    
    ' Create the angular dimension in model space
    Set dimObj = ThisDrawing.ModelSpace.AddDimAngular(angVert, FirstPoint, SecondPoint, TextPoint)
    ZoomAll
    MsgBox "The current value of ExtLine2EndPoint is " & dimObj.ExtLine2EndPoint(0) & ", " & dimObj.ExtLine2EndPoint(1) & ", " & dimObj.ExtLine2EndPoint(2), vbInformation, "ExtLine2EndPoint Example"
    
    ' Change the endpoint of the second extension line
    SecondPoint(0) = 1: SecondPoint(1) = 4: SecondPoint(2) = 0
    dimObj.ExtLine2EndPoint = SecondPoint
    dimObj.Update
    
    ' Return the endpoint of the second extension line
    ' Note that the return value is a Variant
    Dim retPnt As Variant
    retPnt = dimObj.ExtLine2EndPoint
    MsgBox "The new value of ExtLine2EndPoint is " & dimObj.ExtLine2EndPoint(0) & ", " & dimObj.ExtLine2EndPoint(1) & ", " & dimObj.ExtLine2EndPoint(2), vbInformation, "ExtLine2EndPoint Example"
