签名

VBA：

object.ExtensionLineOffset

对象

类型：Dim3PointAngular、DimAligned、DimAngular、DimArcLength、DimDiametric、DimOrdinate、DimRotated

此属性应用于的对象。

属性值

只读：不

类型：双

一个正实数，指定将延伸线偏移到原点之外的距离。

言论

此属性的初始值为 0.0625。

注意：此属性将覆盖给定维度的 DIMEXO 系统变量的值。

例子

VBA：

Sub Example_ExtensionLineOffset()
    ' This example creates a Dim3PointAngular object in model space
    ' and changes the offset of the extension lines using the
    ' ExtensionLineOffset property
    
    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
    
    ' 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)
    ThisDrawing.Application.ZoomAll

    ' Read and display current offset of the extension lines from the control points
    MsgBox "The extension lines are currently offset " & DimPointAngularObj.ExtensionLineOffset & " units"

    ' Change the extension lines offset distance from the control points
    DimPointAngularObj.ExtensionLineOffset = 1.5
    ThisDrawing.Regen acAllViewports
    
    ' Read and display current offset of the extension lines from the control points
    MsgBox "The extension lines are now offset " & DimPointAngularObj.ExtensionLineOffset & " units"
    
End Sub
