sound like a plan ...

What I did was to create a spline curve of the section.

copied it and placed the copied spline curve in to its own layer.

the with the original one (this is for the front section ) I lathe it into 360 around along the Y orientation.. (bty I have the center saucer placed in the center point of the top layout grid ) made up of 80 segments...but only need you need a total of 40. for the front then cut it in half.

then with the copied one (this is for the aft section ) I lathe again with the same settings except I added 160 segments for the aft section so you need 80 section by cutting it half along the Z orientation

(I am thing of add more to the next one) so when I have to stretch this part it hold the shape.. (I am think of subdividing the next one to see if I have better look --- but I like the first way as I have more control of the point and less to work with.)

anyway I pick the points on the aft section (cut this by the X orientation cutting the 80 section too 40 - much easer). and start stretching all the point along the segments. from the top view.

it worked for me until I can improve on it.
