oh u like headaches then? once you get thinking, there's no stopping you and no
telling what you did, aside from the few comments you've made.

bezier perimeter and a top curve = half a walnut shell.
(just invert and y scaled for a bottom half)

evenly space points along these lines
calculate normals and write the mesh
define faces in quads and triangles and define indices
strip edges define union of surfaces .... blah blah

sweep_pnts_array(0.24,0.001,bezier_length(ship_prim)/(79+1)+.0005,ship_prim,0)
sweep_pnts_arrayxy(0.24,0.001,bezier_length(ship_top)/(39+1)+.0005,ship_top,1)
bezierPrismQ(0,0,1.2,1,-90,14,0,1)  //extrudHeight,,,,,slices,sub-edges,close
define number of edges and faces

ship.pov
#include "triangulation.inc"
#include "spheroid_dome.inc"
#include "bezier2.inc"

if you really want to play with it, I'll zip and post the files
