•WHO USES IT?

•WHY THEY USE IT?

CAD is often referred to as computer aided drawing, computer aided design, computer aided drafting or computer assisted design. CAD software is used by architects, engineers, drafters, artists, and others to create precision drawings or technical illustrations. CAD software can be used to create two-dimensional (2D) drawings or three-dimensional (3D) models.

What is it?

CAD is often used by:

Architects

Engineers

Cartographer

Product designer

Who uses it? Why they use it?

design structures such as homes, skyscrapers, shopping malls and government offices

design machines and manufacturing methods, and they specialize in such subjects as aerospace, electricity, mechanics or computer hardware

Design maps – 2D and 3D (google maps, NAV man)

Use CAD to design prototypes of there product for digital proposals. Also print in 3D to make a prototype

• Communicating a message• Drawing is a form of communication• 3 types of communication• Verbal• Non verbal• Written
