Thanks for explaining. Very much appreciated. I'll take a look.

I ended up using loft to create the basic shapes. Then I tweaked the originating curves to the correct side/top profiles which was great as the lofted shape adjusted instantly as I tweaked. Super for 'fine-tuning' a shape. Lastly, I deleted the loft shape, added fillets as I liked and re-lofted. I tried adding fillets with the 'live' loft but things got weird fast. Seems like the "Samardac Method" is a great one for parametric-like modeling. :-)
