Lay a fresh sheet of copier paper on a flat surface and place one side of the fuselage centerline side down.
Take a pencil and trace the outline of the top half of the fuselage, including fin and rudder. Try to ignore any canopy cutouts--draw the line as if the canopy isn't there.
Measure circumferences along the fuselage. There are a lot of ways to do this. A systematic approach is to take some tape that you can easily mark on and cut it into thin strips and place the strips vertically along the fuselage where bulkhead circumference measurements are to be made. Do about 4-7 of these and tape them to the fuselage then place marks where the tape intersects with the centerline on the top and bottom.
Place the taped up fuselage on your drawing and mark the vertical alignment of your tape strips, i.e. place little marks on your drawing where the tape strips are along the top and bottom.
In this step we transfer the measured circumference from the fuselage to the drawing. Do this by removing the first tape from the fuselage and tape it to your drawing, aligning the top tape mark with the top drawing mark. Make sure the other end of the tape aligns with the bottom mark (more or less vertically). Then mark the drawing where ever the bottom mark appears.
Repeat this with all of the tape strips and remove the strips from the drawing.
Lightly connect the dots along the bottom. If the plane features a canopy and a wing fillet, measure and/or estimate where these go and pencil
