What is the primary purpose of CAD software?

The primary purpose of CAD (Computer-Aided Design) software is to assist in designing parts and structures. This software provides engineers and designers with powerful tools for creating detailed and precise drawings, models, and simulations of various objects, ranging from small components to large buildings. With CAD software, users can visualize their designs in 2D or 3D, which aids in both the design process and the eventual manufacturing of those designs. Features such as dimensioning, tolerance checking, and material specification are integral to CAD, enabling designers to ensure that their components meet functional and aesthetic requirements.

While options related to electronic document storage, project management, and market research involve important aspects of engineering and business processes, they do not capture the core functionality of CAD software. The primary focus of CAD is design, making it an essential tool in fields such as engineering, architecture, product design, and manufacturing.
