Creating a path from the conceptualisation of rules, the creation of routines in software that applies these rules, to the manufacture of small prototypes derived from the process is what we know as Parametric Architecture. The creative process in an emergent way, provoking and achieving results from a certain work process based on research means that now, at this precise moment, the computer is of total relevance. We will be introduced to the mastery of 3D digital modelling tools to apply them to the design of shapes and spaces, both the design of their interiors and their exterior skins.
