What is the primary purpose of CAD?

The primary purpose of CAD (Computer-Aided Design) is to facilitate design using computer software. This technology allows designers and engineers to create detailed 2D and 3D representations of objects, which enhances their ability to visualize and manipulate designs with precision. CAD software provides tools for drafting, modeling, and visualizing designs, making it an integral part of the design process in various industries such as architecture, engineering, and manufacturing.

While creating physical prototypes, managing project timelines, and analyzing product performance are important aspects of the overall design and manufacturing process, they are secondary to the main function of CAD. CAD is specifically focused on the design stage, streamlining and improving the efficiency of creating complex designs that can later be turned into prototypes or products.
