I have now started lofting the formers. This is quite easily done; use the 3-view and measure the width and height at each former location, as shown on the attached photo. Then use the knowledge about the shape, i.e. see the previous post, and draw the formers.

Here is what it looks like so far. The next bit is the fuselage at the cockpit section. At this point, I just concentrate on getting the correct external shape.
