Codes and relationship scales in the technical-practical drawing

Cognitive processes of drawing

Abstract

At one time, practical things were considered the objective act of grasping what was valuable and necessary in the execution of work. They were the indispensable foundation for the preparation inherent in governing and controlling the settlement and the construction of the factory. These relations were able to guarantee completeness, coherence, functionality and form. A further sense and meaning were declared and made evident through the recognisable and straightforward building process that, through the practice of building, was positioned as a fact of order for what was granted and not only exclusively obliged. The term civil, a word intrinsic to many historical treatises and manuals of architecture and engineering, meant intelligence, wisdom, recognition and research, a sort of imprinted ethical and, why not, deontological code referring to the practice of doing. The epistemology of modernity differs from that of antiquity in that the disciplines of knowledge are not founded on ethical and moral criteria but rather on formal aspects beyond the 'oxymoron' of modernist ambiguity. Instead, the intention is to anticipate, through the description and knowledge of technical and practical drawing, the fact of solving the questions of construction by using the tool of graphic and geometric representation as a foundation on which to base and refer in preparation for the executive drawing for the building site. Therefore, the presentation must indeed be governed by the gnomonic question. Still, first and foremost, it must correspond to geometric principles and, simultaneously, know how to construct by measuring and calculating the construction. This is an ontological question since the most effective working tool remains, despite the different and relativistic positions, the drawing: the practical drawing, indeed, the one that rigorously declares both the cadastral value and the detail of the structure in which the operations of the invention, that is, finding, searching for an inseparable unit of calculation and measurement and finally of representation, concur and coincide together.
