What is the function of CAD in construction?

The correct choice highlights the function of CAD, or Computer-Aided Design, which is primarily focused on creating digital representations of construction designs. CAD software enables architects and engineers to produce precise drawings and technical illustrations that include the necessary details for a construction project. This digital sketching allows for easy modifications, enhances accuracy, and facilitates collaboration among various stakeholders by providing a clear visual understanding of the project.

Choosing this option is significant because it underscores the importance of digital tools in modern construction practices, facilitating the visualization and planning process before any physical work begins. CAD applications streamline design processes, help in adhering to specifications, and allow for the simulation of various scenarios, which is invaluable in the construction industry.
