Bug in Transform.Scale(Plane, double, double, double)

Hello
I want to transform a sphere to an ellipsoid. So I use Transform.Scale(Plane plane, double x, double y, double z). It appears that I have no effect of y, and same effect of x and y.

    Sphere sphere = new Sphere(Point3d.Origin, 100);
    //Brep ellipsoid = sphere.ToBrep();
    Brep ellipsoid = Brep.CreateFromSphere(sphere);

    ellipsoid.Transform(Transform.Scale(Plane.WorldXY, aa, bb, cc));

    A = ellipsoid;

Hi @laurent_delrieu, try to make it deformable before the transform:

ellipsoid.MakeDeformable();

Thanks, I didn’t thought about this. Because I often use simple non destructive transform…
