The full form of CAD is Computer-Aided Design. CAD refers to advanced software used to create designs and technical drawings in both 2D and 3D. It is widely employed by architects, engineers, drafters, and artists for precision, efficiency, and flexibility in design creation. By integrating hardware and software, CAD allows users to visualize, simulate, and refine their designs from various perspectives, making the entire design process faster and more accurate.
CAD first gained prominence in the 1980s, evolving rapidly alongside advancements in computer technology. Today, CAD software is accessible for most computing devices, making it indispensable across various industries.
Tools for CAD
To utilize CAD software effectively, the following tools are essential:
- High-Quality Graphics Monitor: Ensures clear visualization of detailed designs.
- Light Pen: Enables accurate drawing and interaction with the software.
