軸の周囲のリージョンを指定して、回転ソリッドを作成します。
サポートされているプラットフォーム: Windows のみ
VBA:
RetVal = object.AddRevolvedSolid(Profile, AxisPoint, AxisDir, Angle)
タイプ: Block、ModelSpace、PaperSpace
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: Region
外形線には、Region オブジェクトのみが使用できます。
アクセス: 入力のみ
タイプ: バリアント型(3 要素の倍精度浮動小数点数型配列)
回転軸の始点を指定する 3D WCS 座標。
アクセス: 入力のみ
タイプ: バリアント型(3 要素の倍精度浮動小数点数型配列)
回転軸の方向を指定する 3D ベクトル。
アクセス: 入力のみ
タイプ: 倍精度浮動小数点数型
回転角度をラジアンで表したもの。完全に 1 回転させる場合は 6.28 と入力します。
回転するリージョンは閉じていなければなりません。ブロック内に含まれるオブジェクトを回転させることはできません。回転できるのは、一度に 1 つのオブジェクトのみです。
正の回転方向は、右手の法則にしたがって決定されます。
