What does Computer Aided Design (CAD) primarily assist with?

Computer Aided Design (CAD) is primarily focused on the creation and modification of designs using computer technology. It provides designers and engineers with tools to create precise drawings and models in a digital format, which significantly enhances the design process in various fields such as architecture, engineering, and product design. CAD software allows for the easy manipulation of design elements, enabling users to visualize and iterate their ideas efficiently. This helps in the quick revision of designs, improving accuracy, and facilitating collaboration among team members.

The other options do not accurately reflect the primary function of CAD. Data storage relates to the management of files and data, which is a secondary benefit of using digital tools but not the core purpose of CAD. Internet connectivity is about linking devices and accessing online resources, which is unrelated to the design functions of CAD. Financial accounting pertains to managing finances and ledgers, which is outside the realm of design work. Thus, the essence of CAD lies in its ability to create and modify designs effectively.
