The Ellipsoid command draws a solid NURBS ellipsoid.

#### Command-line options

* Radius: Creates an ellipsoid by defining the half-length of each axis.

  1.Corner: Draws the base ellipse from the center point and a corner of the enclosing rectangle.
* Corner: Draws the base ellipse from two opposite corners of the enclosing rectangle.
* Diameter: Creates an ellipsoid by defining the length of each axis.

  1.Vertical: Draws the base ellipse perpendicular to the construction plane.
* FromFoci: Draws the ellipse from focus points and a point on the curve.

  1.MarkFoci: Places a point object at the focus locations.
* AroundCurve: Draws the base ellipse perpendicular to the picked point on a curve. The third axis will be tangent to the curve.
