VBA：

object.DimensionLineExtend

对象

类型：DimAligned、DimArcLength、DimRotated

此属性应用于的对象。

属性值

只读：不

类型：双

一个正实数，指定将尺寸线延伸到延伸线之外的距离。

言论

此属性的初始值为 0.0000。

注意：此属性将覆盖给定维度的 DIMDLE 系统变量的值。

例子

VBA：

Sub Example_DimensionLineExtend()
   ' This example creates an aligned dimension in model space and
   ' uses DimensionLineExtend to specify the distance the dimension
   ' line extends beyond the extension line when oblique strokes are
   ' drawn instead of arrowheads

    Dim dimObj As AcadDimAligned
    Dim point1(0 To 2) As Double, point2(0 To 2) As Double
    Dim location(0 To 2) As Double
    
    ' Define the dimension
    point1(0) = 5: point1(1) = 5: point1(2) = 0
    point2(0) = 10.123: point2(1) = 5: point2(2) = 0
    location(0) = 5: location(1) = 7: location(2) = 0
    
    ' Create an aligned dimension object in model space
    Set dimObj = ThisDrawing.ModelSpace.AddDimAligned(point1, point2, location)
    dimObj.Arrowhead1Type = acArrowOblique
    dimObj.Arrowhead2Type = acArrowOblique
    
    ThisDrawing.Application.ZoomAll
    
    MsgBox "A new Dimension has been created.  Press any key to extend the dimension lines."
    
    ' Round the distance of the alternate dimension to 0.50 of a unit
    dimObj.DimensionLineExtend = 2
    ThisDrawing.Regen acAllViewports
    
    MsgBox "The dimension lines have been extended to: " & dimObj.DimensionLineExtend
End Sub
