Which of the following is a disadvantage of Computer Aided Design?

The chosen answer highlights a significant concern associated with Computer Aided Design (CAD). One of the disadvantages of CAD systems is the potential for confidential designs to be leaked. As designs are created and stored digitally, they become susceptible to unauthorized access or cyber attacks. If proper security measures are not in place, sensitive information can be exposed to competitors or the public, which could result in financial loss or a competitive disadvantage for a company.

In contrast, the other options represent advantages or positive aspects of using CAD. Enhancing design flexibility allows designers to manipulate and modify designs more easily than traditional methods. Being cost-effective refers to the long-term savings associated with increased efficiency and reduced material wastage. Lastly, requiring less training suggests that user-friendly interfaces can facilitate quicker onboarding for new users, ultimately accelerating the design process. Thus, the correct answer emphasizes a critical risk while the others point to the benefits of employing CAD in design processes.
