The purpose of this paper is to do an analysis of the graphic representation techniques in architecture, seeking in Peirce's Theory of Signs an interpretation of the conventional steps of the architectural design process. A research was conducted in the architecture course in pursuit of a systematization of the information generated at each step of the design process. Finally, it emphasizes the importance of the ability to adapt to the environment, of awareness of the languages, giving the student autonomy to choose the suitable feature.
