指定备用单位的舍入。

支持的平台：仅限 Windows

签名

VBA：

object.AltRoundDistance

对象

类型：DimAligned、DimArcLength、DimDiametric、DimOrdinate、DimRadial 、DimRadialLarge、DimRotated

此属性应用于的对象。

属性值

只读：不

类型：双

一个正实数，表示要将距离舍入到的值。初始值为 0.00。

言论

如果该属性处于打开状态，则此属性将定义要将距离舍入到的数字。AltUnits

注意：此属性将覆盖给定维度的 DIMALTRND 系统变量的值。

例子

VBA：

Sub Example_AltRoundDistance()
   ' This example creates an aligned dimension in model space and
   ' uses AltRoundDistance to set the alternate unit display
   ' of the dimension to rounded values

    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)
    
    ' Enable alternate unit display
    dimObj.AltUnits = True
    
    ThisDrawing.Application.ZoomAll
    
    MsgBox "Press any key to round the alternate dimension unit display to .5"
    
    ' Round the distance of the alternate dimension to 0.50 of a unit
    dimObj.AltRoundDistance = 0.5
    ThisDrawing.Regen acAllViewports
    
    MsgBox "Alternate dimension units have been rounded to: " & dimObj.AltRoundDistance
End Sub
