Mechanical Engineering CAD Foundations: Modeling and Geometric Principles

Computer-Aided Design (CAD) is the backbone of modern mechanical engineering, transforming conceptual sketches into precise physical components. Understanding the mathematical and geometric principles behind CAD software is essential for creating robust, manufacturable designs. In this text-only course, you will transition from foundational geometric theories to advanced solid modeling practices. You will gain a deep conceptual understanding of how CAD engines process shapes, curves, and transformations, enabling you to use any professional CAD tool with confidence and precision. You will learn to: Understand fundamental CAD terminology, coordinate systems, and the core mathematics of spatial design; Apply geometric transformations including translation, scaling, rotation, and reflection; Design mathematical curves and surfaces using Bezier, B-spline, and NURBS formulations; Create solid models using boundary representation and constructive solid geometry; Explore modern CAD trends like parametric modeling, cloud collaboration, and design for additive manufacturing. The curriculum begins with essential definitions and mathematical foundations before progressing to curve generation, solid modeling techniques, and modern industry workflows. You will read detailed explanations and work through conceptual design exercises to solidify your engineering instincts. This course is designed for aspiring mechanical engineers, students, and hobbyists new to CAD, with no prior engineering or modeling experience required.
