Then I drawn two lines (blue) to score the height of the upper curved surface of the fuselage on the SideView, and I used those lines to draw two arcs.




Then I used the “Push/Pull” tool onto major arc to create the upper surface as a solid. Next I used the “Scale” tool to fit the width, then the “Move” tool to fold the small extremity, and the “Scale” again to reduce the height of the arc. Use the inference!






Now I can clean the surface from the useless elements and create a group.
