I'll try to help you sort it out if you like...
You'd like to make a male or female form, half of a tear drop divided at it's center plane, laying on it's side, with the tear drop shape outline in the x-y plane, yes? That will be the contour. The other shape, a large arc that transitions to a very small arc on the small end of the teardrop, which would be the profiles, the large arc transitioning to the small one, would follow the contours' path, yes?
The problem I see is that Partmaster can only interpolate one profile around a contour... as the profiles you'd like use would need to transition from the large end of the teardrop to a virtual point, or tiny arc on the small end of the teardrops contour. Maybe someone has an alternative, but it would seem to require at least z axis roughing and finishing in 2.5 D, or true 3D interpolation to accomplish your job...neither is available in partmaster pro.
