Constructing a simple fuselage

 From:  Stever_uk (STEVER)
I have had some time to play around with MoI.

In the example (see attached) I have created a very basic fuselage type object using the loft.

I then wanted to see if I could do the same but with nice a rounded front and back in one go.

I'm currently playing around with sweep and Network by adding rail curves but at this time having issues with creating round ends

I was wondering how you would tackle this.
