As far as I can see, these shapes are never mentioned again - and certainly are not used for any of the following purposes:

- Show where there is separated and attached flow on existing cars

- Guide the shape of rear extensions

- Show how rear spoilers on sedans should be positioned and shaped

- Allow the assessment of the ‘aerodynamic purity’ of cars

In the real world of road cars, basic shapes like the template are pretty well irrelevant.
In the Preface of his 2nd-Edition, Hucho admonishes us, advising us to learn everything about road vehicle aerodynamics, plus that from other disciplines, such that we may draw on the entire body of knowledge to draw on for solutions.
You'll be in an information desert unless you've explored biomimicry, airships, blimps, blisters, canopies, fairings, radomes, bullet-valves, nozzles, self-powered rail-cars, submarine exterior hulls, torpedoes, projectiles, belly tanks, drop-tanks, towed electronics arrays, antenna housings, etc..
If you'll continue to learn, you'll eventually arrive at a reality which overturns your present rudimentary understanding.
