オブジェクトをコピーするには、そのオブジェクトの Clone 関数を使用します。このメソッドは、元のオブジェクトを複製して新規オブジェクトを作成します。複製オブジェクトの作成後は、データベースに追加する前に修正することができます。オブジェクトを変換するか、またはその位置を変更しない場合、新しいオブジェクトは元のオブジェクトと同じ位置に配置されます。
コピーするオブジェクトが多数ある場合は、 ObjectIdCollection オブジェクトにそれぞれのオブジェクト ID を追加した後で、各オブジェクトを反復処理します。各オブジェクトを反復処理するときに、それぞれのオブジェクトに Clone 関数を使用し、新しいオブジェクトをデータベースに追加します。
次の例では、新しい円を作成し、その円を直接コピーして 2 つ目の円を作成します。

次の例では、コピーする必要のあるオブジェクトを追跡するために ObjectIdCollection オブジェクトを使用します。コレクションにオブジェクト ID を追加した後で、コレクションが反復処理されます。Clone メソッドを使用して新しいオブジェクトを作成し、次にモデル空間に追加します。
