What does "CAD" enable engineers to do?

CAD, or Computer-Aided Design, is a technology that allows engineers and designers to create detailed technical drawings and models through specialized software. This capability includes 2D and 3D modeling, enabling precise design specifications and visual representations of components, systems, or structures. The use of CAD enhances productivity, improves accuracy, and facilitates easier modifications compared to traditional hand-drawn designs.

By generating digital models, engineers can better visualize their work, analyze potential design flaws before production, and collaborate effectively with others involved in the project. CAD software also often includes tools for simulating the performance of designs under various conditions, which is essential for making informed engineering decisions.

In contrast, other choices do not accurately reflect the core functionality of CAD. While physical prototypes are essential for testing designs, they are created after the CAD phase. Marketing strategies are unrelated to CAD, as they pertain to business and promotional activities. Statistical analysis is a different discipline that focuses on data interpretation and is not typically conducted through CAD tools.
