Definition
Computer-Aided Design (CAD) refers to the utilization of computer software to facilitate the design process, allowing designers, engineers, and architects to create precise drawings, schematics, and models. This technology has revolutionized traditional design methods, shifting from manual drafting using pencils and paper to more sophisticated and versatile digital tools.
Examples
- Building Floor Plans: An architect uses CAD software to create detailed and precise floor plans for residential and commercial buildings. This allows for quick revisions and accurate scaling.
- Car Design: Automotive engineers leverage CAD to design various parts of a vehicle, ensuring that each component fits perfectly before production.
- Product Prototyping: Industrial designers use CAD to develop prototypes of consumer products like electronics, ensuring functionality and aesthetics are achieved before mass production.
