2.1 - Introduction
To build a modular product, you will need:
- A Modular Context π (Product), representing the whole model. It has no 3D, just some metadata.
 - Multiple products called Modules π. Each module is a classic Configurable Product, with some extra data to make it work in a modular product.
 
Then only if you need them, you can create:
- Mutliple Compositions π that are used to display predefined compositions of the modular product.
 
Below is a diagram representing all those products:

Example
As an example, if you have the "Sofa Model 1" that can be built using "2 seaters", "3 seaters" and "Corner":
- "Sofa Model 1" is a product without 3D called the Modular Context π.
 - "2 seaters", "3 seaters" and "Corner" are configurable products called Modules π.
