Create an Ellipse as a Polyline or an Ellipse Object *Applies to: AutoCAD R13, 14, 2000, 2000i, 2002, 2004 and 2005*
The PELLIPSE system variable controls whether or
not you create at Ellipse object as a set of Polylines or as a true
Ellipse object. When the value of PELLIPSE is set to 1, a true
Ellipse object is created versus one created with Polyline segments if
the value was set to 0. One of the things that you will notice
is that when working with a true Ellipse and you go to offset it, it
will create the new Ellipse as a Spline. This is untrue if you
create the Ellipse with PELLIPSE set to 0 because when you go to
offset it, the new offset object will be a Polyline like the original.
Note: You also can not use the lengthen command on a Spline object.
