work in progress.

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

http://en.wikipedia.org/wiki/Ellipse

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)"

z()= "0+0.5*Math.sin(theta)*Math.sin(0)-1*Math.sin(theta)*Math.cos(0)"
