Introduction to CAD: Essential 2D Drafting and 3D Modeling

Computer-aided design (CAD) is the backbone of modern engineering, architecture, and product design. Understanding how to translate ideas into precise digital models is a highly valued skill across multiple industries. This text-based course guides you from absolute beginner to a confident CAD practitioner. You will start by understanding core terminology, coordinate systems, and basic geometric shapes, before moving on to advanced parametric modeling concepts and preparing your designs for real-world manufacturing. What you'll learn: Understand foundational CAD terminology, coordinate systems, and drafting standards; Create precise 2D sketches using standard geometric constraints and dimensions; Build 3D solid models using extrusion, revolution, and sweeping techniques; Apply parametric design principles to make your models easily adjustable; Prepare design files for modern manufacturing methods like 3D printing and CNC machining; Practice collaborative design workflows and cloud-based file management. The course begins with essential concepts and drafting rules, gradually progressing to complex 3D assembly modeling and modern design collaboration. Through clear written explanations and structured practice exercises, you will build a solid foundation in digital design. This course is designed for beginners with no prior CAD or engineering experience who want to learn the fundamentals of digital drafting.
