Parametric design and the Sagrada Familia

Abstract

Parametric design is a paradigm for the more effective use of computers in architectural design and practice. Rather than focus on design as a holistic process of formal synthesis, the more localised issue of design development will be discussed, especially with regard to the resolution of complex geometry. The triforium of Gaudí's Sagrada Familia is taken as a case study. Parametric variation is used to define surface geometry consistent with the surviving fragments of plaster models, and what we know of Gaudí's technique.
