What is the primary function of Computer-Aided Design (CAD)?

The primary function of Computer-Aided Design (CAD) is to enable users to create precise drawings, models, and simulations of products directly on a computer. CAD software provides designers with powerful tools to draft and visualize their designs in a digital environment, which enhances the accuracy and efficiency of the design process. By using CAD, engineers and architects can easily manipulate and analyze their designs, run simulations, and make rapid modifications, all of which contribute significantly to streamlining the development workflow.

Other options do not align with the main purpose of CAD. Managing employee productivity, conducting market research, and handling customer relationships are important functions in a business context but are not related to the design and drafting capabilities that CAD provides. Thus, the focus of CAD remains distinctly on the design aspect, making it an essential tool in industries like engineering, architecture, and manufacturing.
