  1. Create a new ellipse. New ellipses are always fully-packed. You'll see an ellipse and a bunch of construction geometry: major diameter, minor diameter, foci.
  2. Select minor diameter line and hit Del. The diameter is gone, but the ellipse remains. How do we get the diameter back?
  3. Select the ellipse and invoke the Show/hide internal geometry command. The diameter is restored.
  4. Now, constrain the major diameter of the ellipse to some length. Select the ellipse and invoke the Show/hide internal geometry command.

Result: Minor diameter and foci are deleted, but the major diameter is kept, because it participates in other constraints. Ellipse's center remains too, because it is inherent, like center of a circle.
