摘要:AbstractIn the course “Analysis of Architectonic Forms” of the Technical School of Architecture of Valencia, students experiment freehand drawing as a tool for understanding the genesis of architecture and its key elements: geometric composition, proportions, rhythms, spatial organization, function, relationship with the environment, etc. Nevertheless, it is necessary a process of “unlearning”, for those who have already internalized the basic fundamentals of drawing and architecture, to be able to propose new architectonic forms not based on logical thinking. To reach so, we point out a number of educational objectives based in concepts (I), processes (II) and attitudes (III), which are supported by the practice of spontaneous drawing and which ultimately result in a more complete training for future architects.
