Which of the following is a function of computer-aided design (CAD) programs?

Computer-aided design (CAD) programs serve a multitude of functions that enhance the architectural design and drafting process. One of the primary advantages of CAD is its ability to create 3D models, which allow architects and designers to visualize structures in a more realistic way. This includes the ability to manipulate the models to examine various perspectives and details, which is an essential aspect of modern architectural design.

Additionally, CAD programs are widely used for drafting and rendering. Drafting involves the precise creation of detailed technical drawings that convey the specifications and dimensions of a design, while rendering refers to the virtual generation of images that represent how a project will look when complete, including materials and lighting.

Furthermore, CAD software facilitates the generation of construction documents, which are crucial deliverables that guide the actual construction process. These documents typically include plans, sections, and details necessary for contractors and builders to accurately construct the designed structure.

Therefore, the correct response reflects the comprehensive capabilities of CAD programs. They can create 3D models, handle drafting and rendering tasks, and generate essential construction documents, making them indispensable tools for architects and designers in the industry.
