The history of CAD engineering is closely tied to the evolution of computer technology. From its early beginnings to the sophisticated tools used today, CAD has revolutionized the design and manufacturing industries.

Early Stages (1950s-1960s):

• Sketchpad (1963): Developed by Ivan Sutherland, Sketchpad was one of the first graphical user interfaces and a precursor to modern CAD systems. It allowed users to create and manipulate drawings directly on a computer screen.

Development of CAD Software (1970s-1980s):

• Early CAD Systems: Companies like Computervision and Applicon developed early commercial CAD systems, primarily used in the aerospace and automotive industries.
• 2D Drafting: These systems focused on 2D drafting, replacing traditional manual drafting methods.

Advancements in 3D Modeling (1990s):

• 3D CAD Software: The introduction of 3D CAD software like SolidWorks and CATIA enabled engineers to create complex 3D models, leading to more accurate and efficient designs.
• Parametric Modeling: Parametric modeling allowed designers to easily modify designs by changing parameters, making the design process more flexible.

Integration and Specialization (2000s-Present):

• BIM (Building Information Modeling): BIM emerged as a specialized form of CAD for the architecture, engineering, and construction (AEC) industry, allowing for comprehensive building design and management.
• Cloud-Based CAD: Cloud-based CAD software has made CAD accessible to a wider audience, enabling collaboration and remote work.
• AI and Machine Learning: Integration of AI and machine learning is enhancing CAD capabilities, automating tasks, and improving design optimization.

Impact on Industries:
