His notebooks are filled with sketches of inventions, anatomical studies, and architectural concepts. THIS INFLUENTIAL WORK IS CONSIDERED THE FIRST PRINTED BOOK ON THE THEORY OF PERSPECTIVE AND PROJECTION DRAWING. DA VINCI EXPLORED THE PRINCIPLES OF PERSPECTIVE AND HOW TO REPRESENT THREE- DIMENSIONAL OBJECTS ON A TWO-DIMENSIONAL SURFACE  GASPARD MONGE (1746- 1818) "GÉOMÉTRIE DESCRIPTIVE" (1801) MONGE'S SEMINAL WORK FORMALIZED THE PRINCIPLES OF ENGINEERING DRAWING AS WE KNOW THEM TODAY.ELLING POINTS. He developed the theory of projecting views of an object onto three mutually perpendicular planes (front, top, and side views). This method, known as orthographic projection, is still  FREEHAND SKETCHING AS THE FOUNDATION: IDEA GENERATION: FREEHAND SKETCHES ARE CRUCIAL IN THE EARLY STAGES OF THE DESIGN PROCESS. THEY ALLOW ENGINEERS AND DESIGNERS TO QUICKLY AND EASILY VISUALIZE AND COMMUNICATE THEIR INITIAL IDEAS. PROBLEM-SOLVING: SKETCHING HELPS IN BRAINSTORMING, EXPLORING DIFFERENT SOLUTIONS, AND REFINING CONCEPTS BEFORE MOVING ON TO MORE DETAILED DRAWINGS. THOUGHT ORGANIZATION: THE ACT OF SKETCHING ITSELF HELPS TO ORGANIZE THOUGHTS, IDENTIFY POTENTIAL PROBLEMS, AND REFINE THE DESIGN.  DRAW I N G IS A FORM OF GRAPHIC COMMUNICATION. IT EXPRESSES IDEAS AND CONVEYS SPECIFIC INFORMATION BY MEANS OF GEOMETRIC SHAPES, LINES, AND DIMENSIONS. THESE ELEMENTS COMPRISE THE L ANGUAGE OF DRAWING THAT IS UNIFORM AND STANDARDIZED THROUGHOUT THE WORLD. SUCCESS ACROSS VARIOUS INDUSTRIES. DRA FT I NG Furniture Drafting It includes not only the making of the working drawing of the various types of the furniture but also the design appropriate to it. Machine Drafting Involves the design, development, and drawing of all mechanical devices from very small machine parts to the largest type of machinery. A few of its specific applications are automotive design, tools, appliances, machinery, engines, and so forth.  DRA FT I NG Architectural Drafting. Involves the working drawings of buildings and structures. The building can be simple cabin or a huge skyscraper. Structural Drafting. Refers to working drawings of steel buildings, bridges, towers, dams, etc.  DRA FT I NG Sheet-Metal Drafting. It is the development of surfaces of various objects made of galvanized iron (GI), steel, aluminum, and copper sheets. Electrical-Electronic Drafting. It pertains to the design, development and drawing of the products and the parts of the products that use electricity as a power source  DRA FT I NG Topographical Drafting. Concerns the layout and drawing of maps: simple street map or a complex contour map. Aeronautical/Aerospace Drafting. Concerned with design, development and drawing of all types of airborne vehicles. These vehicles include everything from balloons to gliders to the most sophisticated type of jet aircraft and all type of space vehicles. DRAFTING Drafting plays a critical role in enabling technological advancement. The increasing complexity of modern challenges necessitates interdisciplinary collaboration and a strong foundation of core skills, which are essential for success across various
