3D Modeling and Digital Prototyping for Modern Engineering

Modern product development no longer starts with flat drawings; today, everything begins with a digital prototype. Understanding how to construct and manipulate three-dimensional objects is an essential skill for any modern designer, engineer, or inventor. This text-only course guides you through the foundational concepts of computer-aided design (CAD) and parametric modeling. You will transition from basic geometric sketching to structuring complex assemblies, preparing you to bring your physical inventions to life in a digital space. What you'll learn: - Understand the core terminology of parametric modeling and the digital product lifecycle. - Master the rules of 2D sketching, constraints, and dimensioning as the basis for 3D shapes. - Apply extrusion, revolution, and sweep operations to generate solid 3D parts. - Create multi-part assemblies and define realistic spatial relationships between components. - Design with modern manufacturing in mind, including basic optimization for 3D printing and CNC machining. - Practice reading engineering requirements and translating them into precise digital prototypes. You will start by learning fundamental spatial concepts and terminology before moving on to step-by-step written exercises that guide you through part creation, assembly configuration, and model validation. This course is designed specifically for beginners, including aspiring engineers, hobbyists, and inventors with no prior CAD or 3D modeling experience.
