||A method to develop skills using digital techniques in architectural and design fields is proposed. Recursive procedures in successive cycles of abstraction are used applied for the urban layout design process. Each configurational cycle (master plan, urban modules, buildings, habitational units) is separated and exaggerated to face the process with pedagogical goals. Urban factors that conform the city are identified in order to classify repetitive urban problems. A patch of the city, in which a master plan is developed, is isolated and is submitted the measurable tests related to the Architectural and Design projecting process, enfatizating the following aspects., its systemic structures, its geometry and its growing. Alometric concepts and growing form analogies are used as scale control method in transformations and in recursive cycles. Based in two potentially recursive theories, fractals and tessellation's theories, a pedagogic procedure oriented to the use of tessellations is proposed using CAD systems tools.
