グループまたは選択セットから、指定された項目を除去します。
サポートされているプラットフォーム: Windows のみ
VBA:
object.RemoveItems Objects
タイプ: Group、SelectionSet
このメソッドが適用されるオブジェクト。
アクセス: 入力のみ
タイプ: バリアント型(オブジェクトの配列)
除去されるオブジェクトの配列。
戻り値はありません。
グループや選択セットから除去された項目は図面内に残りますが、グループや選択セットとの関連はなくなります。これは Clear メソッドによく似ていますが、RemoveItems メソッドでは選択セットのオブジェクトすべてを除去するのではなく、除去する項目をユーザが指定することができます。
このメソッドは、Delete メソッドや Erase メソッドとは異なり、図面からオブジェクトを除去しません。
