|Introduced in version|
A Part Ellipsoid is a parametric solid that can be created with the Part Primitives command. In the coordinate system defined by its DataPlacement property, the axes of the ellipsoid are aligned with the X, Y and Z axes, and therefore its center is positioned at the origin.
A Part Ellipsoid 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 an ellipsoid by changing its DataAngle3 property.
See Part Primitives.
A Part Ellipsoid object created with the scripting example below is shown here.

A Part Ellipsoid 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.
- DataRadius1 (
Length): The radius of the ellipsoid in its Z direction. The default is
- DataRadius2 (
Length): The radius of the ellipsoid in its X direction. The default is
- DataRadius3 (
Length): The radius of the ellipsoid in its Y direction. The default is
- DataAngle1 (
Angle): The start angle of the elliptical sides of the ellipsoid. Valid range:
-90° <= value < 90°. Must be smaller than DataAngle2. The default is
- DataAngle2 (
Angle): The end angle of the elliptical sides of the ellipsoid. Valid range:
-90° < value <= 90°. Must be larger than DataAngle1. The default is
90°. If the total angle of the elliptical sides is smaller than
180°the ellipsoid will be truncated and have a flat face at the top and/or bottom.
- DataAngle3 (
Angle): The total angle of the ellipsoid in its XY plane. Valid range:
0° < value <= 360°. The default is
360°. If it is smaller than
360°the resulting solid will be a segment of an ellipsoid.
A Part Ellipsoid can be created with the
addObject() method of the document:
ellipsoid = FreeCAD.ActiveDocument.addObject("Part::Ellipsoid", "myEllipsoid")
"myEllipsoid"is the name for the object.
- The function returns the newly created object.
import FreeCAD as App doc = App.activeDocument() ellipsoid = doc.addObject("Part::Ellipsoid", "myEllipsoid") ellipsoid.Radius1 = 2 ellipsoid.Radius2 = 4 ellipsoid.Radius3 = 6 ellipsoid.Angle1 = -90 ellipsoid.Angle2 = 50 ellipsoid.Angle3 = 300 ellipsoid.Placement = App.Placement(App.Vector(1, 2, 3), App.Rotation(15, 0, 20)) doc.recompute()
