This book covers the fundamentals of engineering drawing and computer-aided design for first-year engineering students. Engineering graphics begins with geometric modelling basics, which provides the foundational principles for representing objects. This starts with the simplest element, the projection of points, and builds complexity with the projection of lines, where their true length, inclinations, and traces are determined. This extends further to the projection of planes, analysing their orientation and size in various views. These concepts culminate in the projection of solids, where three-dimensional objects like prisms and pyramids are depicted based on their position relative to the reference planes. To understand internal details, the section of solids is used, imagining the object cut by an imaginary plane to reveal its interior cross-section. For fabrication purposes, developments of surfaces are created, which are the unfolded, flat patterns of all the solid's faces. To generate a three-dimensional view on a two-dimensional sheet, isometric projection is employed, using a specific set of axes to convey depth and form without perspective. Finally, these skills are applied to create clear and accurate pictorial views of solids and objects, which are essential for visualization, technical communication, and manufacturing.
