The history of CAD technology is a fascinating journey from manual drafting to sophisticated computer-aided design systems. Understanding this evolution provides context for the role of CAD Technicians today.

Early Beginnings:

• Manual Drafting: Before CAD, technical drawings were created manually using pencils, rulers, and other drafting tools. This process was time-consuming and prone to errors.
• Sketchpad (1963): Ivan Sutherland's Sketchpad at MIT is considered the first graphical user interface and a precursor to CAD. It allowed users to create and manipulate drawings on a computer screen.

Development of CAD Systems:

• 1970s: The first commercial CAD systems emerged, primarily used in the automotive and aerospace industries. These systems were expensive and required specialized hardware.
• 1980s: CAD technology became more accessible with the development of personal computers. AutoCAD, one of the most popular CAD software programs, was released in 1982.

Advancements in CAD Technology:

• 3D Modeling: CAD systems evolved to support 3D modeling, allowing designers to create realistic representations of objects.
• Parametric Modeling: Parametric modeling enabled designers to create designs that could be easily modified by changing parameters.
• Building Information Modeling (BIM): BIM emerged as a comprehensive approach to managing building design and construction information.

CAD in India:

• Early Adoption: CAD technology was introduced in India in the late 1980s and early 1990s, primarily in large engineering and manufacturing companies.
• Growth and Expansion: With the growth of the Indian economy, CAD technology has become more widely adopted across various industries.
• Current Trends: The use of CAD in India is driven by the need for efficient design, accurate documentation, and collaboration in large-scale projects.

Future of CAD:

• Cloud-Based CAD: Cloud-based CAD systems are becoming more popular, offering greater flexibility and collaboration.
• Artificial Intelligence (AI): AI is being integrated into CAD software to automate tasks and improve design efficiency.
• Virtual Reality (VR) and Augmented Reality (AR): VR and AR technologies are being used to visualize and interact with CAD models in new ways.
