Computer-aided design (CAD) is a technology that enables designers and engineers to create precise drawings and models using computer software. It streamlines the design process, allowing for greater accuracy and efficiency in creating everything from simple sketches to complex 3D models. CAD is widely used in various fields, including architecture, engineering, and manufacturing. With CAD software, users can visualize their designs in a virtual environment, making it easier to identify potential issues before physical production. This technology not only enhances creativity but also facilitates collaboration among team members, as designs can be easily shared and modified in real-time.
