指定禁止在备用维度值中显示前导零。

支持的平台：仅限 Windows

签名

VBA：

object.AltToleranceSuppressLeadingZeros

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：布尔

True：禁止在交替维度中显示前导零。例如，0.5000 变为 .5000。
False：不要在交替维度中隐藏前导零。

言论

此属性的初始值为。False

注意：此属性将覆盖给定维度的 DIMALTTZ 系统变量的值。

例子

VBA：

Sub Example_AltToleranceSuppressLeadingZeros()
   ' This example creates an aligned dimension in model space and
   ' uses AltToleranceSuppressLeadingZeros to toggle the display of leading zeros
   ' in the alternate dimension tolerance display

    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) = 5.01: 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)
    
    ' Set up alternate unit tolerance display
    dimObj.AltUnits = True
    dimObj.ToleranceDisplay = acTolLimits
    
    ThisDrawing.Application.ZoomAll
    
Toggle:
    Select Case MsgBox("Press OK to toggle the display of leading zeros in the alternate dimension tolerance", vbOKCancel)
        Case vbOK
            ' Toggle the display of leading zeros for the alternate dimension tolerance value
            dimObj.AltToleranceSuppressLeadingZeros = Not (dimObj.AltToleranceSuppressLeadingZeros)
            ThisDrawing.Regen acAllViewports
        Case vbCancel
            Exit Sub
    End Select
    
    GoTo Toggle
End Sub
