Thanks Michael

I understood what your meant even without the images or extra post and thankyou for you help and advice. This is pretty much how I have gone about creating the fin and cockpit in my model. I've booleaned off the areas of the aircraft where the fillets begin and used curves to define the ends but the transitions of the curves are just too tough for nurbs it seems and results in a lot of surface joints that look bad on the meshed model.

I still leave it open to Burrman, Brian or anybody who wants to have a go to show me how this aircraft should be done with nurbs. I would be most interested to see their effort and how they went about it. All the reference photos they need, blueprints and MoI setup is contained in the first post of this thread. My only requirement is that they closely capture the look of this aircraft as it easy to distort the shape of the aircraft to suit the software.

The challenge is there and there is no time requirement
