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
在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
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 is5mm. - 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 is90°. If the total angle of the arc profile is smaller than180°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 is360°. If it is smaller than360°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()
