Computer-Aided Design (CAD): A Practical Guide to LibreCAD for Engineering, Home Science and Vocational Education provides a practical and application-oriented introduction to computer-aided drafting and design. The book explains the transition from conventional paper-based drawing to precise digital drafting and introduces readers to the concepts, tools and workflow required for creating professional 2D technical drawings.The book places particular emphasis on LibreCAD, a free and open-source 2D CAD application suitable for students, beginners and users working with lightweight computer systems. It systematically explains the LibreCAD interface, menu bar, toolbars, dialogue boxes, drawing templates, unit settings, coordinate systems, drawing tools, modify tools and dimensioning facilities.Particular attention is given to precision drafting through Grid, Snap, Ortho Mode, Tracking and Object Snap (OSNAP). The book also covers layers, blocks, hatch patterns, CAD standards, annotation, dimensioning, file formats such as DXF and DWG, PDF export, print settings, scale and plot preview. These topics help learners develop organized, accurate and professionally presentable drawings.
