Architectural representation

Descriptive geometry course
Descriptive geometry is a conceptual tool for learning to see the volumetry of buildings represented in two dimensions (in plan, section and elevation), whether they already exist or are still at the design stage.
This tool is understood as a mise en abyme of three-dimensional space, which must be understood as a perfectly coherent whole based on its planar representations. It is an abstract and unusual language that enables us to solve certain spatial problems using general and rigorous methods, by transferring these problems from geometry in space to plane geometry.
This subject is therefore essential to the architect’s training, as it develops his capacity and freedom for spatial design. It is an absolutely direct mediator between imagination and project design.

Les deux méthodes principales étudiées sont celles qui permettent de résoudre les problèmes d’intersection et les problèmes de mesure.
L’initiation à la méthode d’intersection se fait en privilégiant essentiellement le tracé des ombres.
Les méthodes de déplacement sont abordées plus rapidement pour mesurer les vraies grandeurs des éléments obliques ; elles sont validées ensuite sur une maquette.
