The curve on both sides of the point follows the movement; the section of the curve between the next points changes shape. Point at the curve between two points or within a closed curve and drag the mouse to shift the entire curve without distorting the form.
２つの制御点の間にある曲線、または閉じられた曲線の表面にマウスを合わせ、マウスボタンを押した状態でドラッグすると、変形させずに曲線全体を移動させることができます。
