|Part → Primitives → Sphere|
|Introduced in version|
The Part Sphere command creates a parametric sphere solid. It is the result of revolving a circular arc profile around an axis. In the coordinate system defined by its DataPlacement property, the center of the sphere is positioned at the origin, and its axis of revolution is the Z axis.
A Part Sphere can be truncated at the top and/or bottom by changing its DataAngle1 and/or DataAngle2 properties. It can be turned into a segment of a sphere by changing its DataAngle3 property.
- There are several ways to invoke the command:
- The sphere is created.
- Optionally change the dimensions and DataPlacement of the sphere by doing one of the following:
A Part Sphere object created with the scripting example below is shown here.
- 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:
The object has the same attachment properties as a Part Part2DObject.
- DataRadius (
Length): The radius of the sphere. The default is
- DataAngle1 (
Angle): The start angle of the circular arc profile of the sphere. Valid range:
-90° <= value <= 90°. May not be equal to DataAngle2. The default is
- DataAngle2 (
Angle): The end angle of the circular arc profile of the sphere. Valid range:
-90° <= value <= 90°. May not be equal to DataAngle1. 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.
- DataAngle3 (
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.
A Part Sphere can be created with the
addObject() method of the document:
sphere = FreeCAD.ActiveDocument.addObject("Part::Sphere", "mySphere")
"mySphere"is the name for the object.
- The function returns the newly created object.
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()
