貝茲
Available in: Sketch
使用沿著貝茲曲線控制多邊形上的點來繪製多點的貝茲曲線。貝茲曲線會隨著其控制多邊形的路徑。
- 按一下
。 - 按一下來開始,再按一下來設定點,連按兩下來結束。
貝茲曲線 (藍色)、控制多邊形 (黑色) 與控制點 (白色圓圈) 的範例。
- 請確定已取消選取「草圖」工具列中的「貝茲曲線」草圖工具。
- 按一下並拖曳貝茲曲線控制多邊形上的任何控制點 (白色點) 來調整曲線。
您可以使用貝茲控制點來標註尺寸:
您可以將貝茲控制點與限制條件一起使用。例如,下方圖片中的兩個橘色強調顯示點是限制為垂直的:
Trimming a Bezier curve results in the trimmed portion being removed, with the remaining section of the curve retaining the original number of degrees and control points:
Original curve (left), Trimming at the construction line (middle), result of the trim (right)
Splitting a Bezier curve splits the original curve into two new curves on either side of the split point. Each curve has the same number of degrees and control points. The original curve's shape and length remains the same.
Original curve (left), Splitting the curve (middle), result of the split (right)
Both new curves are coincident to each other. Moving one curve also moves the other. However, control points for each curve are independent from each other.
Moving either curve moves both, since they are coincident at the split point.
