Introduction to Computer-Aided Design (CAD)

• Computer-Aided Design (CAD) has revolutionized industries like engineering, architecture, product design, and manufacturing.
• CAD software is used by professionals to create, modify, analyze, and optimize designs with precision and efficiency.

History of CAD

• The CAD concept began in the mid-20th century due to computer evolution.
• Ivan Sutherland's Sketchpad in 1963, created a base for interactive graphics and design.
• CAD gained traction in the 1970s and 1980s with advancements in computing power.
• AutoCAD is a cornerstone program that arose from this period.

Key Features of CAD Software

• Modern CAD software enhances the design process through various features.
• Designers can create 2D and 3D representations of objects for detailed visualization and analysis.
• Parametric design enables automatic updates to associated components when changes are made.
• CAD tools often simulate real-world conditions like stress testing or fluid dynamics.
• Cloud-based CAD platforms allow real-time team collaboration, improving efficiency.
• CAD software commonly integrates with Computer-Aided Manufacturing (CAM) systems for a smooth design-to-production process.

Applications of CAD
