Introduction to CAD and Engineering Graphics

Technical drawing is the universal language of engineering, and computer-aided design (CAD) is the modern tool used to speak it. This text-based course introduces you to the essential concepts of CAD and engineering graphics, guiding you from basic geometric constructions to modern digital drafting standards. You will transition from understanding fundamental drawing principles to reading and creating precise technical representations. Through clear explanations and structured written exercises, you will develop the spatial reasoning and technical skills required to interpret and draft engineering designs. What you'll learn: Understand the core principles of engineering graphics, orthographic projections, and isometric views; Master the fundamental tools and terminology used in modern CAD software environments; Practice dimensioning and tolerancing techniques to ensure manufacturing accuracy; Apply parametric modeling concepts to create adaptable and scalable digital designs; Explore modern collaborative CAD workflows and file management practices. The course begins with foundational definitions, drawing standards, and basic geometric concepts, before progressing to projections and digital CAD workflows. Designed specifically for beginners, this course requires no prior drafting or engineering experience. Start reading today to unlock your spatial design capabilities.
