The history of CAD engineering is intertwined with the evolution of computing technology. From its humble beginnings to its current sophisticated state, CAD has revolutionized the design and manufacturing industries.

• Early Days (1950s-1960s): The earliest forms of CAD emerged in the 1950s with the development of computer graphics. Ivan Sutherland's Sketchpad, created in 1963, is considered a pioneering achievement in interactive computer graphics and laid the foundation for modern CAD systems.
• Mainframe Era (1970s): In the 1970s, CAD systems began to be used in industries such as aerospace and automotive. These systems were expensive and required powerful mainframe computers.
• Personal Computers (1980s): The advent of personal computers in the 1980s made CAD technology more accessible to smaller companies and individual designers. AutoCAD, released in 1982, became a widely used CAD software.
• 3D Modeling (1990s): The 1990s saw the rise of 3D modeling in CAD. Software like SolidWorks and CATIA enabled engineers to create realistic 3D models of products, facilitating better visualization and analysis.
• Modern CAD (2000s-Present): Today, CAD software is highly sophisticated, offering advanced features such as simulation, analysis, and collaboration tools. Cloud-based CAD platforms are also gaining popularity, enabling designers to work remotely and collaborate more effectively.

Impact on Industries:

• Automotive: CAD has enabled automotive engineers to design and develop vehicles more efficiently, reducing design cycles and improving product quality.
• Aerospace: CAD is essential for designing aircraft and spacecraft, ensuring safety and performance.
• Construction: CAD is used to create detailed architectural drawings and structural models, facilitating the construction of buildings and infrastructure.
• Manufacturing: CAD is used to design and manufacture a wide range of products, from consumer goods to industrial equipment.
