## Description

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.

## Usage

See Part Primitives.

## Example

Part Ellipsoid from the scripting example

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

## Properties

A Part Ellipsoid 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.

Ellipsoid

• DataRadius1 (`Length`): The radius of the ellipsoid in its Z direction. The default is `2mm`.
• DataRadius2 (`Length`): The radius of the ellipsoid in its X direction. The default is `4mm`.
• DataRadius3 (`Length`): The radius of the ellipsoid in its Y direction. The default is `4mm`.
• 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 `-90°`.
• 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.

## Scripting

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

```ellipsoid = FreeCAD.ActiveDocument.addObject("Part::Ellipsoid", "myEllipsoid")
```
• Where `"myEllipsoid"` is the name for the object.
• The function returns the newly created object.

Example:

```import FreeCAD as App

doc = App.activeDocument()
