ハッチングに外側ループを追加します。
サポートされているプラットフォーム: Windows のみ
VBA:
object.AppendOuterLoop loop
戻り値はありません。
AddHatch メソッドを使用して Hatch オブジェクトを作成した後、外側のループを追加します。外側のループは閉じたループで、内側のループより先に作成しなければなりません。有効な外側のループを作成したら、AppendInnerLoop メソッドを使用して 1 回に 1 つずつ内側のループを追加します。
ハッチング境界を定義したら、Evaluate メソッドを使用して境界用のハッチング線分または塗り潰しを計算します。次に、Regen メソッドを使用してハッチングの表示を更新します。
VBA:
Sub Example_AppendOuterLoop() ' This example creates an associative hatch in model space, and then creates an outer loop for the hatch. Dim hatchObj As AcadHatch Dim patternName As String Dim PatternType As Long Dim bAssociativity As Boolean ' Define the hatch patternName = "ANSI31" PatternType = 0 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 Dim startAngle As Double Dim endAngle As Double center(0) = 5: center(1) = 3: center(2) = 0 radius = 1 startAngle = 0 endAngle = 3.141592 Set outerLoop(0) = ThisDrawing.ModelSpace.AddArc(center, radius, startAngle, endAngle) Set outerLoop(1) = ThisDrawing.ModelSpace.AddLine(outerLoop(0).startPoint, outerLoop(0).endPoint) ' Append the outer loop to the hatch object, and display the hatch hatchObj.AppendOuterLoop (outerLoop) hatchObj.Evaluate ZoomAll End Sub
