Introduction
CAD (Computer-Aided Design) is a groundbreaking technology used to create precise 2D drawings and 3D models of products before they’re physically built. It’s a blend of hardware and software that empowers architects, engineers, artists, and designers to visualize, modify, and optimize designs with unmatched accuracy.
Key Highlights:
- Digital Prototyping: Replace physical prototypes with virtual models.
- Collaboration: Share designs globally for instant feedback.
- Efficiency: Slash production time and costs.
History of CAD: From Sketchpad to Smart Tools
CAD’s journey began in 1963 when Ivan Sutherland developed Sketchpad, the first GUI-based design system, during his MIT PhD. This innovation laid the foundation for modern CAD.
Second Milestone:
In 1971, P.J. Haranty founded MCS, launching ADAM (Automated Drafting And Machining), the first commercial CAD software. By 2025, CAD has evolved into AI-driven, cloud-based platforms.
