描述
创建一种圆锥曲线(Create a conic)是草图工作台几何图形工具栏中的一个图标按钮,它集合了多种基于圆锥截面创建曲线的工具。点击此图标右侧的向下箭头会在下侧展开工具集,此时来选取其中的一种工具。
以不同的方式圆锥曲线
- Ellipse by center : 根据中点、长半轴点与短半轴点来绘制一个椭圆。
- Ellipse by 3 points : 根据长轴(也就是两个点)与短半轴点来绘制一个椭圆。
- Arc of ellipse : Draws an arc of ellipse by 根据中点、长半轴点、起始点与终点来绘制一段对应椭圆上的弧。
- Arc of hyperbola: v0.17及其以上版本 绘制一条双曲线上的弧。
- Arc of parabola: v0.17及其以上版本 绘制一条抛物线上的弧。
