Final answer:
CAD software has revolutionized architectural design by providing realistic, accurate, and affordable 3D visualizations, which can be used to create detailed plans and live models, negating the need for physical prototypes.
Step-by-step explanation:
One true statement about Computer Aided Design (CAD) is that it has profoundly impacted architectural design since its invention in 1961. CAD software provides realistic representations, speed, accuracy, and affordability, which are invaluable tools for architects. These programs have evolved to include 3D visualizations and simulations, enabling architects to forgo physical models. Instead, architects can create detailed plans, conduct virtual tours, and produce live 3-dimensional models viewable from multiple perspectives, significantly aiding in the construction and presentation phases of their projects.
