Computer-aided design or CAD involves the use of computers and software to digitally create engineering drawings and models to aid in tooling and product design. This program, part of the Fundamentals of Tool Design Video Series, explores the tools and techniques used within these four fundamental computer-aided design categories:
The 2D CAD segment examines orthographic projection, workflow, and detailing.
The 3D modeling segment details the use of 2D sketching, feature-based parametric 3D modeling, and design editing.
The segment on 3D assembly design features an emphasis on part mating/alignment, interference detection, and dynamic motion.
The CAD analysis segment is broken down into four basic principles:
