What is one major advantage of Computer Aided Design (CAD)?

The major advantage of Computer Aided Design (CAD) is the ability to edit designs easily and quickly. CAD software allows designers to make modifications in real-time, which significantly enhances efficiency. This capability means that designers can iterate and refine their work without the need for starting from scratch, allowing for greater flexibility in the design process. Furthermore, changes can be easily applied across multiple views of a design, ensuring consistency and saving time in the revision phase.

In contrast, the other options do not effectively represent the advantages of CAD. While some hardware requirements may be minimal depending on the software used, many CAD applications can demand considerable processing power for more intricate tasks. The statement that designs cannot be copied is misleading; CAD files can indeed be duplicated and shared, a common practice in collaborative environments. Additionally, while CAD can facilitate the creation of complex designs, its main strength lies in the efficiency of modifications rather than complexity itself. Thus, editing designs quickly and easily is the most significant benefit of using CAD technology.
