CAD and 3D modeling/animation systems are a special type of graphics production tool that allows users to create precise drawings and models. These systems first appeared in businesses and industries and later made their way to classrooms, where they are commonly used in vocational-technical programs to teach architecture and engineering skills. CAD systems can also be employed in art classrooms to teach drawing concepts and be used to create sophisticated visual effects.
