The book Dibujo Industrial by Jesús Félez and Mª Luisa Martínez is a foundational text in engineering graphics, widely used for teaching technical drawing and standardization in industrial design. It covers both the theoretical principles of geometry and the practical application of international standards (ISO/UNE). Key Content and Features
The manual covers essential engineering graphic skills, including: Isometries and 3D visualization. Especejamiento (detail drawing and exploded views). Simbología and Cortes (symbols and cross-sections). jesus felez dibujo industrial pdf
One of the most cited sections in Dibujo Industrial concerns the standardized representation of threaded fasteners. Félez clarifies a common confusion: the difference between simplified, schematic, and realistic thread representation. He provides tables for pitch diameters, drill depths for tapped holes, and proper callouts (e.g., M10 × 1.5 – 6H). A practical exercise asks students to correct a deliberately erroneous drawing where a blind tapped hole lacks a thread runout and an incorrect tap drill depth. By solving this, students learn that a missing 30° chamfer on a bolt head or an omitted thread runout can cause assembly interference. Such attention to detail reflects Félez’s industry experience, likely drawn from Spanish manufacturing sectors like automotive and machinery. The book Dibujo Industrial by Jesús Félez and
