Final answer:
CAD programs enhance design ability with realistic 3D visualizations, faster design iterations, and increased accuracy, while reducing costs and the need for physical models.
Step-by-step explanation:
CAD programs enhance the ability to design by providing architects and engineers with tools for realistic representations, improved speed, enhanced accuracy, and affordability in the design process. These computer-aided design and drafting systems allow for the creation of intricate 3D visualizations and simulations, eliminating the need for physical models. This streamlines the workflow from conceptual design to the construction of architectural projects, making it easier to communicate ideas and make necessary adjustments.
Virtual tours and 3D models offer exact views from different angles, facilitating better understanding and collaboration among designers, clients, and construction teams. For instance, the Boeing 777 design process used sophisticated CAD software, which reduced the need for physical mockups and accelerated the manufacturing process. In architecture, the possibility of conceptualizing and realizing designs has also expanded vastly due to CAD's capabilities.
