<p>A parametric Ellipsoid solid is available from the Create Primitives dialogue in the Part workbench.
|

</p><p>The Create Primitives dialogue can be accessed via the <a href="Part_CreatePrimitives.html" title="Part CreatePrimitives">CreatePrimitives</a> icon <a href="https://www.freecadweb.org/wiki/index.php?title=File:Part_CreatePrimitives.png" class="image"><img alt="Part CreatePrimitives.png" src="32px-Part_CreatePrimitives.png" width="32" height="32" srcset="/wiki/images/thumb/8/8a/Part_CreatePrimitives.png/48px-Part_CreatePrimitives.png 1.5x, /wiki/images/8/8a/Part_CreatePrimitives.png 2x" /></a> located in the Part menu or the Part toolbar, in the Part Workbench.

</p><p>The shape produced is limited in FreeCAD to being a solid (optionally truncated) spheroid, the shape you would create by rotating an ellipse around one of its axis. By default it is a <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Oblate_spheroid">oblate_spheroid</a>, the shape you would create by rotating an ellipse around its minor axis. The parameters can be changed to form a <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Prolate_spheroid">prolate_spheroid</a>.
|
|
</p><p>The default spheroid in FreeCAD 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.
|
|
</p><p>In mathematics, an <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Ellipsoid">Ellipsoid</a> would have an elliptical cross section in all three planes.
