Understanding CAD: The Foundation of Digital Drafting CAD (Computer-Aided Design) revolutionized architectural drafting by replacing manual hand drawings with precise digital schematics. Tools like AutoCAD allow architects and designers to create detailed 2D plans and, increasingly, 3D models with high geometric accuracy. CAD excels at producing construction documents, technical schematics, and layouts, making it indispensable for projects where clear, precise technical drawings are required. However, CAD’s focus is primarily on the geometry and visual representation of individual components, with limited integration of metadata or project-wide information.
