平面を定義する 3 点を指定して、3DSolid オブジェクトの切断面を作成します。
サポートされているプラットフォーム: Windows のみ
VBA:
RetVal = object.SliceSolid(Point1, Point2, Point3, Negative)
タイプ: 3DSolid
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(3 要素の倍精度浮動小数点数型配列)
1 番目の点を指定する 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)
2 番目の点を指定する 3D WCS 座標。

ソリッドの平面の負の側にある部分を返すかどうかを指定します。True の場合、AutoCAD は元のソリッドの平面の負の法線側にある部分を含む新規の Acad3DSolid オブジェクトを作成します。
追加の注意はありません。
