角度寸法以外のすべての寸法タイプについての変換寸法計測値の接頭表記を指定します。

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.AltTextPrefix

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: 文字列

変換単位寸法値の接頭表記。

注意

このプロパティの初期値は "" です。

設定されている接頭表記をオフにするには、このプロパティを単一のピリオド(.)に設定します。

注: このプロパティは、指定された寸法でシステム変数 DIMAPOST[併記接頭/接尾表記]の値を変更します。

例

VBA:

Sub Example_AltTextPrefix()
   ' This example creates an aligned dimension in model space and
   ' uses AltTextPrefix to allow the user to change the text prefix 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
    Dim prefix As String
    
    ' 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)
    
    ' Enable alternate unit display
    dimObj.AltUnits = True
    
    ThisDrawing.Application.ZoomAll

    ' Allow the user to change the text prefix for the alternate dimension
    prefix = InputBox("Enter a new text prefix for the alternate dimension", "Alternate Dimension Prefix", "PREFIX:")
    dimObj.AltTextPrefix = prefix   ' Commit changes to prefix
    
    ThisDrawing.Regen acAllViewports
    
    ' Read back and display the alternate dimension text prefix
    prefix = dimObj.AltTextPrefix
    If prefix <> "" Then
        MsgBox "The prefix of the alternate dimension has been changed to: " & prefix
    Else
        MsgBox "The prefix of the alternate dimension has been removed"
    End If
End Sub
