Description

描述

根据position, angle1, angle2, angle3, radius1 与 radius2参数创建一个简单的参数化环面。

A Part Torus can be turned into a segment of a torus by changing its 数据Angle3 property. By changing its 数据Angle1 and/or 数据Angle2 properties the swept profile can become a segment of a circle.

如何使用

在零件工作台中点击环面图标。这会在原点(point 0,0,0)处创建一个环面。三个角度参数(angle1, angle2, angle3)与两个半径参数(radius1 , radius2)用于确定参数化环面，详情请看下段文字。

Example

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

Notes

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

将Radius1参数的值指定为20 mm。

Data

Attachment

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

Torus

Radius1: 小圆盘圆周运动所绕圆环的半径
Radius2: 定义环面形状的小圆盘的半径
Angle1: 用于切割/定义环面小圆盘的第1个角度参数
Angle2: 用于切割/定义环面小圆盘的第2个角度参数
Angle3: 用于定义环面运动圆周的第3个角度参数

Scripting

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

torus = FreeCAD.ActiveDocument.addObject("Part::Torus", "myTorus")

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

Example:

import FreeCAD as App

doc = App.activeDocument()

torus = doc.addObject("Part::Torus", "myTorus")
torus.Radius1 = 20
torus.Radius2 = 10
torus.Angle1 = -90
torus.Angle2 = 45
torus.Angle3 = 270
torus.Placement = App.Placement(App.Vector(1, 2, 3), App.Rotation(30, 45, 10))

doc.recompute()
