描述
底图三圆周点绘弧工具通过输入4个点:中点、半径、第一个点、最后一点,或拾取的切线,或上述若干组合,在当前的工作平面上创建一条圆弧。它将根据Draft Tray中的Draft Linestyle设置来创建对应圆弧。
根据圆周上的3个点而定义的弧
如何使用
- Press the Draft Arc 3Points button, or press A then T keys.
- Click a first point on the 3D view, or type a coordinate and press the add point button.
- Click a second point on the 3D view, or enter a radius value.
- Click a third point in the 3D view, or enter a start angle.
