Hi Torsten,
I use Solid models for everything, then split up the model into the parts I want. I'll use a 3-view plan and make sketches of the fuse sections, then place those sketches on the corresponding section plane and loft them into a solid, very similar to the wing lofting a few pages back. Then "shell" out the solid fuse to the former thickness I want and split the resulting body in half. After that, I'll use half of the fuse body to split into formers, and the other half for making stringer notches, then mirror the notches onto the former half. The reason I use half and half is that to get the guide curve for the stringer notches, I use the full half body and a plane and use "Sketch tools, intersect curve" and use that for the guide curve, one whole spline the length of the fuse, not just pieces, then swept-cut the notch. It sounds more complicated than it is, here's a few pics to help you get the idea.
