Description

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。

Usage

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

Cone Radius 1 - 定义底面弧或圆的半径 Radius 2 - 定义顶面弧或圆的半径 Height - 零件圆锥体的高度 Angle - 定义截断圆锥体顶面与底面上弧或圆的角度值。默认值360创建的顶底皆为圆面，较小值将创建出不完整的部分圆锥，具体形状取决于实际角度与两个半径所定义的弧，乃至顶面与底面。

• 数据Radius 1: Radius of the arc or circle defining the lower face
• 数据Radius 2: Radius of the arc or circle defining the upper face
• 数据Height: Height of the Part Cone
• 数据Angle: 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.

Scripting

A Part Cone can be created using the following function:

cone = FreeCAD.ActiveDocument.addObject("Part::Cone", "myCone")

• Where "myCone" is the name for the object.
• The function returns the newly created object.
