I am trying to figure out how to design a model airplane fuselage in geomagic design elements. I have a good idea on how to use a lofted surface to get the fuselage shape, but I cannot figure out how to draw formers to fit inside the lofted surface

I'm relatively new to GM, and am using GM Design V16. But...
I tried a simple loft between two planes...a circle to a square. Then inserted a plane, parallel and halfway between the two ends. This is the point for my "former". I then did a Section View on the former plane, activated Sketch on that plane, and did a Project-to-Sketch of the section view face. This gives a sketch of the cross section of the loft at that plane, which is what I assume a former is. Hope this is what you want.
