Historical Evolution of Technical Drawing in Engineering

Technical Drawing is based on standard rules established to be applied in technical documentation allowing communication between collaborators in the development of a project. Teaching Technical Drawing to engineering students has been progressed over the years in the history of engineering: Leonardo da Vinci, based on the resources and expertise achieved at his time, contributed to the two-dimensional graphical representation of three-dimensional machines supported in perspectives, shadows and descriptive notes; the influence of Gaspar Monge in the graphical documentation of a project is enormous, with his new science the Descriptive Geometry; the director of the first school of engineering in Portugal, Alfredo Bensaude, recognizes the practice in the execution of drawings as essential for the training of engineers. The text is focused in a brief historical evolution of the Technical Drawing as a science applied in projects and in the importance of its introduction in the engineering schools curricular programs.
