My own naive idea is to use analyticCurve3D but i haven't seen any example on a family of analyticCurve3D, so each is drawn as a single analyticCurve3D.
the match is close but not very accurate
An ellipse in general position can be expressed parametrically as the path of a point (X(t),Y(t)), where
Minimum = 0
Maximum = 2*Math.PI
Variable = "theta"
X() = "1.4+1.4*Math.cos(theta)*Math.cos(0)-1.4*Math.sin(theta)*Math.sin(0)"
