A Part Sphere can be truncated at the top and/or bottom by changing its {{PropertyData|Angle1}} and/or {{PropertyData|Angle2}} properties. It can be turned into a segment of a sphere by changing its {{PropertyData|Angle3}} property.

'''Result:''' The sphere will be positioned at origin (point 0,0,0) on creation. The angle parameters permit to make a portion of sphere instead of a full sphere (they are set to 360° by default).

The properties of the object can be edited, either in the [[Property_editor|Property editor]] or by double-clicking the object in the [[Tree_view|Tree view]].

A Part Sphere object created with the [[#Scripting|scripting example]] below is shown here.

A Part Sphere object is derived from a [[Part_Feature|Part Feature]] object and inherits all its properties. It also has the following additional properties:

{{TitleProperty|Sphere}}
{{TitleProperty|Attachment}}


The object has the same attachment properties as a [[Part_Part2DObject#Data|Part Part2DObject]].
* {{PropertyData|Radius:}} Radius of the sphere
* {{PropertyData|Angle 1:}} 1nd angle to cut / define the sphere

由于很难描述angle 1、angle 2、angle 3这三个参数的意义,因此以下列图示来向您展示关于angle 1 = -45°, angle 2 = 45° 与 angle 3 = 90°时的效果,从而对此进行解释。


* {{PropertyData|Radius|Length}}: The radius of the sphere. The default is {{Value|5mm}}.
[[File:SphereCutThreeAngles.jpg|400px]]
* {{PropertyData|Angle1|Angle}}: The start angle of the circular arc profile of the sphere. Valid range: {{Value|-90° &lt;&#61; value &lt;&#61; 90°}}. May not be equal to {{PropertyData|Angle2}}. The default is {{Value|-90°}}.
* {{PropertyData|Angle2|Angle}}: The end angle of the circular arc profile of the sphere. Valid range: {{Value|-90° &lt;&#61; value &lt;&#61; 90°}}. May not be equal to {{PropertyData|Angle1}}. The default is {{Value|90°}}. If the total angle of the arc profile is smaller than {{Value|180°}} the sphere will be truncated and have a flat face at the top and/or bottom.
* {{PropertyData|Angle3|Angle}}: The total angle of revolution of the sphere. Valid range: {{Value|0° &lt; value &lt;&#61; 360°}}. The default is {{Value|360°}}. If it is smaller than {{Value|360°}} the resulting solid will be a segment of a sphere.

Description

描述

利用位置、角度1、角度2、角度3与半径参数创建一个简单的参数化球体。

A Part Sphere can be truncated at the top and/or bottom by changing its 数据Angle1 and/or 数据Angle2 properties. It can be turned into a segment of a sphere by changing its 数据Angle3 property.

Usage

如何使用

零件工作台中点击球体图标。球体在创建时会被定位在原点(point 0,0,0)处。角度参数确定了所创的是局部球体,而非完整的球体(角度参数的默认设置值为360°)。

Example

Part Sphere from the scripting example

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

Notes

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

A Part Sphere object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties:

Data

Attachment

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

Sphere

  • 数据Radius (Length): The radius of the sphere. The default is 5mm.
  • 数据Angle1 (Angle): The start angle of the circular arc profile of the sphere. Valid range: -90° <= value <= 90°. May not be equal to 数据Angle2. The default is -90°.
  • 数据Angle2 (Angle): The end angle of the circular arc profile of the sphere. Valid range: -90° <= value <= 90°. May not be equal to 数据Angle1. The default is 90°. If the total angle of the arc profile is smaller than 180° the sphere will be truncated and have a flat face at the top and/or bottom.
  • 数据Angle3 (Angle): The total angle of revolution of the sphere. Valid range: 0° < value <= 360°. The default is 360°. If it is smaller than 360° the resulting solid will be a segment of a sphere.

Scripting

See also: Autogenerated API documentation, Part scripting and FreeCAD Scripting Basics.

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

sphere = FreeCAD.ActiveDocument.addObject("Part::Sphere", "mySphere")
  • Where "mySphere" is the name for the object.
  • The function returns the newly created object.

Example:

import FreeCAD as App

doc = App.activeDocument()

sphere = doc.addObject("Part::Sphere", "mySphere")
sphere.Radius = 20
sphere.Angle1 = -30
sphere.Angle2 = 45
sphere.Angle3 = 90
sphere.Placement = App.Placement(App.Vector(3, 9, 11), App.Rotation(75, 60, 30))

doc.recompute()
