Description

A Part Sphere can be truncated at the top and/or bottom by changing its DateAngle1 and/or DateAngle2 properties. It can be turned into a segment of a sphere by changing its DateAngle3 property.

Usage

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

• DateRadius (Length): The radius of the sphere. The default is 5mm.
• DateAngle1 (Angle): The start angle of the circular arc profile of the sphere. Valid range: -90° <= value <= 90°. May not be equal to DateAngle2. The default is -90°.
• DateAngle2 (Angle): The end angle of the circular arc profile of the sphere. Valid range: -90° <= value <= 90°. May not be equal to DateAngle1. 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.
• DateAngle3 (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()
