指定除角度之外的所有尺寸的单位格式。

支持的平台：仅限 Windows

签名

VBA：

object.UnitsFormat

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：枚举acDimLUnits

acDimLScientific
acDimLDecimal
acDimLEngineering
acDimLArchitectural
acDimLFractional
acDimLWindowsDesktop

言论

此属性的初始值为。acDimLDecimal

如果此属性设置为，则和属性指定的格式将用于设置十进制值的格式。acDimLDecimalDecimalSeparatorPrimaryUnitsPrecision

若要创建堆叠体系结构或分数单位格式，请使用该属性。FractionFormat

注意：此属性将覆盖给定维度的 DIMLUNIT 系统变量的值。

例子

VBA：

Sub Example_UnitsFormat()
   ' This example creates an aligned dimension in model space and
   ' uses UnitsFormat to cycle through some common unit formats
   ' for the dimension

    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) = 0: point1(1) = 5: point1(2) = 0
    point2(0) = 5.12345678: 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)
    ThisDrawing.Application.ZoomAll
    
    ' Cycle through common unit formats
    
    dimObj.UnitsFormat = acDimLScientific     ' Change format to Scientific
    ThisDrawing.Regen acAllViewports
    MsgBox "The dimension units are now set to Scientific"
    
    dimObj.UnitsFormat = acDimLDecimal        ' Change format to Decimal
    ThisDrawing.Regen acAllViewports
    MsgBox "The dimension units are now set to Decimal"
    
    dimObj.UnitsFormat = acDimLArchitectural  ' Change format to Architectural
    ThisDrawing.Regen acAllViewports
    MsgBox "The dimension units are now set to Architectural"
    
    dimObj.UnitsFormat = acDimLWindowsDesktop ' Change format to WindowsDesktop
    ThisDrawing.Regen acAllViewports
    MsgBox "The dimension units are now set to Windows Desktop"

End Sub
