How to recreate an ellipse from an ellipse fragment?

With circles we can use Circle:Points.
Can a trimmed curve that used to represent an ellipse be used to recreate it ?

Hi Thomas

Use _MarkFoci to generate the ellipse’s foci from the segment and _Ellipse with the _FromFoci option.

Note that in the latter you need to be able to select the minor access point on the segment to ensure a precise match - if it doesn’t fall within it you can select another point on the curve but you may not get a precise match to the original, in which case you may have to tweak with scaling.
