AltUnitsScale プロパティ(ActiveX)

変換単位の尺度を指定します。

サポートされているプラットフォーム: Windows のみ

構文と要素

VBA:

object.AltUnitsScale

object

タイプ: DimAligned、DimArcLength、DimDiametric、DimOrdinate、DimRadial、DimRadialLarge、DimRotated

このプロパティが適用されるオブジェクト。

プロパティの値

読み込み専用: いいえ

タイプ: 倍精度浮動小数点数型

変換単位に適用される尺度係数。

注意

AltUnits プロパティがオンである場合、このプロパティは長さ寸法に尺度を掛けて、変換寸法の計測システムでの値を生成します。初期値は、1 インチに対するミリメートルの値を表しています。

このプロパティの初期値は 25.4000 です。

注: このプロパティは、指定された寸法でシステム変数 DIMALTF[併記変換係数]の値を変更します。

例

VBA:

Sub Example_AltUnitsScale()
    ' This example creates an aligned dimension in model space and
    ' uses AltUnitsScale to cycle through some common scales
    ' for the alternate 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: 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
    
    ' Enable display of alternate units
    dimObj.AltUnits = True
      
    ' Cycle through some common dimension scales
    
    dimObj.AltUnitsScale = 1         ' Change scale to Inches
    ThisDrawing.Regen acAllViewports
    MsgBox "The alternate dimension units are now set to inches"
    
    dimObj.AltUnitsScale = 25.4     ' Change scale to Millimeters (default)
    ThisDrawing.Regen acAllViewports
    MsgBox "The alternate dimension units are now set to millimeters"
    
    dimObj.AltUnitsScale = 2.54      ' Change scale to Centimeters
    ThisDrawing.Regen acAllViewports
    MsgBox "The alternate dimension units are now set to centimeters"

End Sub
