Thanks Andrei! Your videos made me believe I stand a better chances with MoI to achieve what I need.

The video where you make a loft of a Boeing 747 gave me some great insight to loft behavior. I always draw my splines with interpolation points but started using control points instead. As you mentioned, and the results prove, to keep minimum control points and keep the same profile right through the loft. I want to try this method first and see how good it would work for my shape. In GMD you need to use guide curves between lofts otherwise you end up with waves all over. Im very curious to see how it would work because I will probably need to start from the largest profile and copy it from start to end? Do you think this method will work for my shape?
