How Computer-Aided Design Changed the World

Computer-aided design (CAD) has evolved over the decades and changed the world for the better.

CAD is software used by engineers, designers, architects, and others to digitally mock-up ideas.

This has revolutionized ideation, making it easier and more accessible to bring new ideas to life.

The 1970s marked the beginning of blueprinting, with mocking-up and prototyping becoming crucial to many industries.

However, this process was not yet digitized, relying on drafting tables, pens, rules, curves, templates, and scales.

This method was time-consuming, prone to error, and inaccessible to many due to the high cost of tools.

CAD has made it easier and more accessible to access the tools needed to make new ideas come to life.
