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.

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.
