Hi,

The Ellipse class have an overloaded constructor which takes arguments corresponding to the data you have.

From docs:
public Ellipse(
Point3d center,
Vector3d unitNormal,
Vector3d majorAxis,
double radiusRatio,
double startAngle,
double endAngle
);

So, you can create the ellipse this way:

Ellipse ellipse = new Ellipse(pt1, Vector3d.Zaxis, pt2 - pt1, 0.5, 0.0, Math.PI * 2.0);
