Part Cone/zh-cn

描述
在零件工作台中，可以通过零件工具栏、Part菜单（中的primitives子菜单）或Create Primitives（创建图元）对话框来创建参数化的截断零件圆锥图元.

下图展示了"Angle"为270度且其他参数为默认值的效果.

如何使用
点击位于零件工作台中的图标.

默认值是根据定义的两个半径radius1、radius2、高度以及角度参数来创建一个截断的参数化圆锥. 默认的圆锥被创建在原点(point 0,0,0)处. 角度参数确定了所创建的部分圆锥（默认设置值为360°）, 而radius1与radius2则分别对应于截断圆柱体底部与顶部的半径.

The cone properties can later be edited, either in the Property editor or by double-clicking the cone in the Tree view.

选项

 * : Radius of the arc or circle defining the lower face
 * Radius of the arc or circle defining the upper face
 * : Height of the Part Cone
 * : Number of degrees of the arc or circles defining the upper and lower faces of the truncated cone. The default 360° creates circular faces, a lower value will create a portion of a cone as defined by upper and lower faces each with edges defined by an arc of the number of degrees and two radii.
