Hello Jean-Jacques,
what do you mean by "too slow"?
If you mean, "too difficult to access geometry", you can try Geom_SurfaceOfRevolution with a trimmed half of your Geom_Ellipse and an axis trough its focal points.

Ellipsoïde
Is it an easy way to do an ellipsoïde of revolution ? I manage to do it with Geom_Ellipse and BRepPrimAPI_MakeRevolution but it too slow.
Help me, please.
