LineweightDisplay プロパティ(ActiveX)

図面のモデル空間で、線の太さを表示するかどうかを指定します。

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.LineweightDisplay

object

タイプ: DatabasePreferences

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: ブール型

• True: モデル空間で線の太さを表示します。
• False: モデル空間で線の太さを表示しません。

注意

このプロパティの初期値は True です。

1 ピクセルを超えるピクセルで表される線の太さを使用していると、AutoCAD の再作図にかかる時間が増えます。太い線を使用して作業していて AutoCAD の処理速度が低下する場合には、このプロパティを False に設定します。

例

VBA:

Sub Example_LineweightDisplay()
    ' This example reads and modifies the preference value that controls
    ' whether symbol names may include extended character sets, or more
    ' than 31 characters.
    '
    ' When finished, this example resets the preference value back to
    ' its original value.
    
    Dim ACADPref As AcadDatabasePreferences
    Dim originalValue As Variant, newValue As Variant
    
    ' Get the user preferences object
    Set ACADPref = ThisDrawing.preferences
    
    ' Read and display the original value
    originalValue = ACADPref.LineWeightDisplay
    MsgBox "The LineweightDisplay preference is set to: " & originalValue

    ' Modify the LineweightDisplay preference by toggling the value
    ACADPref.LineWeightDisplay = Not (ACADPref.LineWeightDisplay)
    newValue = ACADPref.LineWeightDisplay
    MsgBox "The LineweightDisplay preference has been set to: " & newValue

    ' Reset the preference back to its original value
    '
    ' * Note: Comment out this last section to leave the change to
    '         this preference in effect
    ACADPref.LineWeightDisplay = originalValue
    MsgBox "The LineweightDisplay preference was reset back to: " & originalValue
End Sub
