Thinking parametric design: introducing parametric Gaudi

This paper presents an innovative methodology for parametric design called Design Procedures (DP) and shows how it is applied to the columns of the Expiatory Temple of the Sagrada Familia. Design Procedures are actions that generate parametric models where geometrical components are consider as variables. A brief introduction on parametric design is followed by illustrated explanations of the traditional forms of parametric models. Design Procedures is presented as an alternative to overcome the topological and geometrical limitations of traditional parametric models. The DP is able to generate all original designs by Gaudi plus an infinite number of new designs.
