In this project we will demonstrate the possibilities and importance of the exploration of resources from the digital image rendering technology in the initial stage of architectonic designs (preliminary studies). The possibilities of the interaction between simplified models of computer aided designs and the representative drawings of the architect’s expression will be evaluated, showing the potential of these resources in the development of an idea, thus highlighting criteria as agility of the process and facility of interaction. The work will be developed through the analysis of design samples, where the interactive interfaces between drawings and drafts, the modeling of solids, 2D drawings and ‘real time’ animated representation will be demonstrated.
