Introduction to Computer Aided Design and Geometric Modeling

Computer Aided Design (CAD) is the backbone of modern engineering, architecture, and product design, turning conceptual ideas into precise digital models. Understanding the underlying mathematics, computer graphics principles, and geometric transformations is essential for creating accurate and efficient designs. In this course, you will transition from a beginner to understanding how CAD software processes shapes, curves, and 3D spaces, enabling you to work with design tools more effectively. You will learn to: 1. Understand the core principles of computer graphics and how CAD systems render objects. 2. Apply geometric transformations to rotate, scale, and translate 2D and 3D models. 3. Analyze geometric curves and surfaces, including Bezier and B-spline representations. 4. Explore the fundamentals of finite element methods for basic structural analysis. 5. Discover modern collaborative CAD workflows and cloud-based design practices. 6. Practice translating physical design requirements into precise digital coordinate systems. The course begins with foundational definitions of coordinate systems and computer graphics, then guides you step-by-step through mathematical modeling, 3D transformations, and introductory numerical analysis. Designed specifically for beginners, this text-only course requires no prior engineering or programming experience.
