ExtensionLineExtend プロパティ(ActiveX)

寸法補助線が寸法線を越えて延長される距離を指定します。

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.ExtensionLineExtend

object

タイプ: Dim3PointAngular、DimAligned、DimAngular、DimArcLength、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

寸法線が寸法補助線を越えて延長される距離を指定する正の実数。

注意

このプロパティの初期値は 0.1800 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 DIMEXE[寸法補助線延長長さ]の値を変更します。

例

VBA:

Sub Example_ExtensionLineExtend()
    ' This example creates a Dim3PointAngular object in model space
    ' and changes the length of the extension line to extend 1.5 units past
    ' the dimension using the ExtensionLineExtend property
    
    Dim DimPointAngularObj As AcadDim3PointAngular
    Dim AngleVertex(0 To 2) As Double
    Dim FirstPoint(0 To 2) As Double, SecondPoint(0 To 2) As Double
    Dim TextPoint(0 To 2) As Double
    
    ' Define the new Dim3PointAngular object
    AngleVertex(0) = 0: AngleVertex(1) = 0: AngleVertex(2) = 0
    FirstPoint(0) = 2: FirstPoint(1) = 2: FirstPoint(2) = 0
    SecondPoint(0) = 1: SecondPoint(1) = 4: SecondPoint(2) = 0
    TextPoint(0) = 6: TextPoint(1) = 6: TextPoint(2) = 0

    ' Create the new Dim3PointAngular object in model space
    Set DimPointAngularObj = ThisDrawing.ModelSpace.AddDim3PointAngular(AngleVertex, FirstPoint, SecondPoint, TextPoint)
    ThisDrawing.Application.ZoomAll

    ' Read and display current extension line extend length
    MsgBox "The extension line currently extends " & DimPointAngularObj.ExtensionLineExtend & " units past the dimension"

    ' Change the extension line extend length to extend 1.5
    ' units past the dimension
    DimPointAngularObj.ExtensionLineExtend = 1.5
    ThisDrawing.Regen acAllViewports
    
    ' Read and display current extension line extend length
    MsgBox "The extension line now extends " & DimPointAngularObj.ExtensionLineExtend & " units past the dimension"
    
End Sub
