Rear Curve

There are 2 ways to do the Rear Curve..... The easiest is to extend the top curve on the center plane around the rear end 
The other way is to pull the body shape past the center line plane and then cut the body surface with the centerline plane. The first way is easier, but here is a look at the second way.

The Rear Curve is across the center line. It starts at the elevation of the bottom of the Skirt and continues to the top elevation.  If these elevations are not used, the lofted surface is drawn down in back and bumps up in front giving a shape you will not like.

These 3 curves are enough to loft a surface.  Use More if you need to for surface definition.

This lofted surface is not perfect, but it is close.  The next step is to Analyze and Fair the Surface.
