If the ideal taper in the side profile is maximum of 22 degrees, then what is the ideal plan taper? This will greatly shorten the length of the back of the body.
The plan contour would mimic the contour in elevation.Everything depends on where the max roof camber point is with respect to the point of max body width,as this is the zero-point for beginning the plan taper.And the pan-taper would never exceed 22-degrees as well.
On the 'Template',technically,the zero points are at the same location,as we're working with a body of revolution.
In the real world though,the body needs to be more narrow,so we have to morph the top and side contours together best we can.
As Frank Lee has mentioned a number of times,if the body is 'tall' let width be the dominant factor for the taper.
If the car is wider,use the height.
If they're the same,do each equally.
