Part Ellipsoid

Description
The Part Ellipsoid command creates a parametric ellipsoid solid.

FreeCAD creates an ellipsoid, which will have a circle for any cross section parallel to the XY plane. The cross section parallel to the other two planes will be an ellipse.

By default, the ellipsoid is positioned with its mass center at the origin (0,0,0).



Usage

 * 1) There are several ways to invoke the command:
 * 2) * Press the button.
 * 3) * Select the option from the menu.
 * 4) * Select the option from the menu.
 * 5) Set options and press.
 * 6) To close the dialog press.

Example


A Part Ellipsoid object with the values of the bottom scripting example are shown here.

Properties
See also: Property editor.

A Part Ellipsoid object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties:

Data

 * By default the minor radius parallel to the Z-axis,
 * By default the major radius parallel to the XY plane, it is also the maximum radius of the circular cross section
 * By default the major radius parallel to the YZ plane, it is also the maximum radius of the angular cross section
 * Lower truncation of the ellipsoid, parallel to the circular cross section (-90 degrees in a full spheroid)
 * Upper truncation of the ellipsoid, parallel to the circular cross section (90 degrees in a full spheroid)
 * Angle of rotation of the elliptical cross section (360 degrees in a full spheroid)

Scripting
A Part Ellipsoid is created with the method of the document.


 * Where is the name for the object. The name must be unique for the entire document.
 * The function returns the newly created object.

The is the user editable name for the object. It can be easily changed by

You can access and modify attributes of the object. For example, you may wish to modify the three radii and the three angles of the ellipsoid.

The result will be a part of an ellipsoid.

You can change its placement and orientation with:
