The creation of the library relies on a preliminary study of each architectural element to define the dimensions and the various shapes in time and space.

This step is important because good parameters and good building methods depend on it. It must cover at best all the existing cases and allow us to keep only the minimal number of parameters allowing the building of the 3D virtual object. For some kinds of gothic vaults for instance, few parameters are required: all the other dimensions can be deduced and the creation can be carried out following building rules.

Architectural components are first theoretically studied for various styles (ancient, classic, gothic, Asian styles...) from bibliography and also from building practices.
