How to create a solid 3D ellipsoidal in CST

Hello all,
I am trying to create a solid 3D ellipsoidal in CST.
I will be glad if some one can help me to understand how should I do it?
Also I like to know how should I JOIN 2 curves after trim and how to make them a solid?
Thank you
Gal

You can create a normal sphere. After creating sphere transform the sphere and chose scale. In sclae uncheck the Sclae uniform option. From there you can scale the sphere accordingly.
For your questions about curves its better if you link the picture of what you mean.
