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。

The default Part Cone is truncated. It can be turned into a full, untruncated, cone by changing its 数据Radius1 or 数据Radius2 property to zero. It can be turned into a segment of a cone by changing its 数据Angle property.

Usage

如何使用

点击位于零件工作台中的图标。

Example

A Part Cone object created with the scripting example below is shown here.

Notes

A Part Cone can also be created with the Part Primitives command. With that command you can specify the dimensions and placement at creation time.

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。

Data

Attachment

The object has the same attachment properties as a Part Part2DObject.

Cone

数据Radius1 (Length): The radius of the bottom face of the cone. Can be 0mm if 数据Radius2 is larger than 0mm. The default is 2mm.
数据Radius2 (Length): The radius of the top face of the cone. Can be 0mm if 数据Radius1 is larger than 0mm. The default is 4mm.
数据Height (Length): The height of the cone. The default is 10mm.
数据Angle (Angle): The angle of the circular arc that defines the top and bottom face of the cone. Valid range: 0° < value <= 360°. The default is 360°. If it is smaller than 360° the resulting solid will be a segment of a cone.

Scripting

A Part Cone can be created with the addObject() method of the document:

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

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

Example:

import FreeCAD as App

doc = App.activeDocument()

cone = doc.addObject("Part::Cone", "myCone")
cone.Radius1 = 5
cone.Radius2 = 10
cone.Height = 50
cone.Angle = 270
cone.Placement = App.Placement(App.Vector(1, 2, 3), App.Rotation(30, 60, 15))

doc.recompute()

-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。

+A Part Cone object is derived from a [[Part_Feature|Part Feature]] object and inherits all its properties. It also has the following additional properties:
-* {{PropertyData|Height}}: Height of the Part Cone
-* {{PropertyData|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.
