One of the biggest challenges for tuners is changing the proportions of an automobile, which can happen either vertically or horizontally. The three basic concepts in the field of custom car building are Chopping, Channeling and sectioning.
Sectioning is much more complicated than chopping, where the roof of a car is lowered and channeling, which is only possible with cars with ladder frame construction, and a lowering brings without doing the modifications to the suspension. In the so-called sectioning a horizontal piece of the body of the car is taken out, and moved the upper half of the car closer to the lower half of the body. As a result, the proportions are very much changed and you get a lot of applause for it in the hot-rod scene.
An illustrative example based on a model car in the scale 1: 25 is to illustrate the process: The most difficult process in the sectioning is the placement of the cuts. Start by cutting off a 0,3 cm wide tape equivalent to 7,5 cm on an 1: 1 model and attach it to your model car. Adding the width of the saw blade to the width of the tape will give you the maximum amount you can take horizontally. This is true to scale to about 0,5 cm and ensures that the proportions of the car are already changing dramatically. Then take a pencil and mark the corners to draw a guide for the incisions. After the incision you have to remove the tape and cut the plastic between the markings with a utility knife and a fine saw.
After this process, you have two body parts, as you have taken out a piece horizontally. Smooth the corners and edges with a file and then test whether the two parts of the body fit seamlessly together again. Due to this extreme modification of the body, the parts of the interior must be adapted. These are reduced by the same amount in height as the body. The underbody needs the same modifications as the bodywork and the interior, which is why the alternator and the air filter must also be placed lower. It makes sense to adapt the entire motor unit to the visual changes.
Of course that had not happened yet!
