The shortest way is one sketch and then 3 features, Revolve, Extrude, Extrude. Attach your attempt here.

Hi Phuc,

The only way to learn SW or any other 3D software is put your head into it. If someone guide you, then for that moment you will find a way. But in future if you have same issue then that person is not there for you maybe. So find your way yourself.

Anyways, I have found where you had stuck. See the attached image.

not sure what is going on or why this part needs to be made in one sketch....but it can be done with some advanced techniques...I have started models and gotten to the drawing and then decided to scrap the whole thing for a better modeling technique.  Sometimes you have to take the long road and that road will help you decided best practices for what you try to do in the future. 

      Some parts start with material and you cut away what you don't want like if you where machining it.  Other parts you can build with the pancake one extrude over another.  During design time I may start with either of these two methods, or if it is a similar part to one that I have already done I will go with the final method.....the base revolve and then revolve cut for round parts.
