PatternDouble プロパティ(ActiveX)

ユーザ定義ハッチングがダブル ハッチング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.PatternDouble

object

タイプ: Hatch

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: ダブル ハッチング パターンを使用します。
• False: ダブル ハッチング パターンを使用しません。

注意

PatternType プロパティが acHatchPatternTypePreDefined または acHatchPatternTypeCustomDefined に設定されている場合、PatternDouble プロパティは使用されません。

注: このプロパティの値は、システム変数 HPDOUBLE に格納されます。

例

VBA:

Sub Example_PatternDouble()
    ' This example creates an associative hatch in model space.
    ' It then returns whether or not the pattern is doubled, and
    ' then changes that value.
    
    Dim hatchObj As AcadHatch
    Dim patternName As String
    Dim PatternType As Long
    Dim bAssociativity As Boolean
    
    ' Define the hatch
    patternName = "ansi31"
    PatternType = acHatchPatternTypePreDefined
    bAssociativity = True
    
    ' Create the associative Hatch object
    Set hatchObj = ThisDrawing.ModelSpace.AddHatch(PatternType, patternName, bAssociativity)
    
    ' Create the outer loop for the hatch.
    ' An arc and a line are used to create a closed loop.
    
    Dim outerLoop(0 To 1) As AcadEntity
    Dim center(0 To 2) As Double
    Dim radius As Double

    radius = 0.5
    Set innerLoop2(0) = ThisDrawing.ModelSpace.AddCircle(center, radius)
    hatchObj.AppendInnerLoop (innerLoop2)
