Which of these statements is true about CAD?

The statement that CAD (Computer-Aided Design) enables easy editing of designs is true because one of the primary advantages of CAD software is its flexibility in modifying designs. CAD allows designers to make alterations quickly, whether it's adjusting dimensions, changing materials, or trying out new configurations. This efficiency enhances productivity and creativity, as designers can explore different ideas without the need for extensive redraws, which would be time-consuming in traditional hand-drawn methods.

In a collaborative environment, this capacity for easy editing also facilitates teamwork, as multiple designers can contribute and revise a project seamlessly. This aspect of CAD is particularly valuable in industries such as architecture, engineering, and product design, where iterative design processes are crucial to the development of high-quality products.

Regarding the other options, sharing CAD files can often be easier due to digital formats, CAD does not inherently lower production quality (in fact, it can improve quality through precision), and while some CAD files can be large, many applications have been developed to optimize file size and storage efficiency.
