•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

ACTIVITY 1USING TOOLS IN GOOGLE SKETCHUP
COPY & PASTE THE FILE INTO YOUR FOLDER
• FOLLOW THE 8117 PATH
• 8117/STUDENT DATA/WORK HAND-OUT AREA/TAS/YEAR 7/MR DAVIS/MYCAR.SKP
• COPY & THEN PASTE INTO YOUR FOLDER
• YOUR JOB IS TO FIX THIS CAR
•WHEN YOUR HAPPY WITH HOW THE CAR LOOKS YOU MAY ALSO ADD SOME MODIFICATIONS TO THE CAR

WHEN COMPONENTS ARE NOT USED IN CONSTRUCTION OF 3D MODELLING
IT IS DISASTROUS!
