Rounded top of extruded object

[Anonymous]

Hello, new to Fusion 360 (and CAD). I am trying to design a bird and I am making the body by sketching using the spline tool and then extruding as you can see in the picture below. Now obviously a bird does not have a flat top or side surface and I wanted to know is there a way to make the body more round (and like an actual bird). I tried using the fillet tool but that did not seem to work (maybe I am using it wrong ?). 

I also considered using revolve instead of extrude which does a pretty okay job except there is a hole through the middle. Could you somehow revolve about the spline line? 

Any help would be very much appreciated; even giving me an idea of what to search to help me solve this problem. 

Thank You.

You will need to attach your model so the Fusion users can use it to assist you.  If you do not know how to attach your Fusion 360 follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save to your hard drive. Then use the Attachments section of a forum post to attach it.

Thanks for what?  You did not attach your model.

Actually I did attach it to my original poste as shown in screenshot below. But thanks for the snarky response.

Sorry I did not expect you to add it to the original post.  One possibility is to use a Loft to add rounded sides to the body.  This is a loft from the outside surface to a point 0.75"from the body.  Model is attached.

Wow this works very nicely. A very simple solution that I did not think of. Thank you very much!
