Say I want to model a fighter jets fuselage like F22, F35, Su 27, etc they have a detailed fuselage profile even if I use the cross-section drawing as a reference the surface still does not satisfy. what is the method you guys use approach to this?. loft? sweep? subd or network curve?
Please see the Level 1 and 2 Rhino Training for the basics of NURBS modeling. Start on something simpler.
The “Trace Images” tutorial in the Level 1 guide the Jim referenced will be a good one for you when you work that far through the progressive series.
