Desenho TÃcnico Moderno: A Comprehensive Guide to Technical Drawing
Desenho TÃcnico Moderno is a book written by Arlindo Silva, Carlos Tavares Ribeiro, JoÃo Dias and Luis Sousa, published by LIDEL (BRASIL) in 2008. It is a comprehensive guide to technical drawing, covering topics such as engineering graphics, geometric constructions, orthographic projections, dimensioning, tolerancing, sections, auxiliary views, perspective drawing, descriptive geometry, curves and surfaces, computer-aided design and more. The book is intended for current and future engineering professionals, as well as students and teachers of technical drawing. It includes exercises at the end of each chapter and a set of transparencies to support the classes.
The book is available in PDF format for free download from the Internet Archive[^1^]. It is also available for purchase from Google Books[^2^] and Indica Livros[^3^]. The book is written in Portuguese and has 724 pages. It is the ninth edition of the book, which was revised and expanded to include the specificities of civil engineering and architecture teaching and design.
If you are interested in learning or improving your skills in technical drawing, Desenho TÃcnico Moderno is a valuable resource that covers both the theoretical and practical aspects of this discipline. It is a modern and updated book that reflects the development of computer-aided design and the conversion of work methodologies in the last decades.In this article, we will review some of the main topics covered by Desenho TÃcnico Moderno and provide some examples and exercises to illustrate them.
Engineering Graphics
Engineering graphics is the language of engineering, used to communicate technical information through drawings, diagrams and symbols. Engineering graphics follows a set of standards and conventions that ensure clarity, accuracy and consistency. Some of the basic elements of engineering graphics are:
Lines: used to represent edges, contours, dimensions, axes, etc. There are different types of lines, such as continuous, dashed, dotted, chain, etc., each with a specific meaning and application.
Views: used to show the shape and size of an object from different angles. There are different types of views, such as front, top, side, isometric, oblique, etc., each with a specific projection method and orientation.
Scales: used to represent the ratio between the actual size of an object and its size on the drawing. There are different types of scales, such as natural, reduced, enlarged, etc., each with a specific notation and application.
Lettering: used to write text on the drawing, such as titles, labels, notes, dimensions, etc. Lettering should be clear, legible and uniform.
Engineering graphics also involves the use of various tools and techniques to create and modify drawings, such as compasses, rulers, protractors, pencils, erasers, etc., as well as software applications that allow for computer-aided design (CAD).
Example
The following figure shows an example of an engineering drawing of a hexagonal bolt. It includes three views (front, top and side), dimensions (in millimeters), scale (1:2), lettering (in Arial font) and lines (continuous for visible edges and dashed for hidden edges).

Exercise
Draw an engineering drawing of a cylindrical rod with a diameter of 20 mm and a length of 100 mm. Include two views (front and side), dimensions (in millimeters), scale (1:1), lettering (in Times New Roman font) and lines (continuous for visible edges and dashed for hidden edges). a474f39169
