Mr. DavisDay 1

Objective

• SWBAT– Identify the uses of CAD software by

building models in Google SketchUp

Drafting? Engineering Drawing?

2-D

• Maps

2-D

• Diagram / Plan

2-D vs. 3-D

• Traditional 3-D drawing – Isometric projection

Limits of 3-D in 2-D?

• Hard to rotate / see from all sides

Solution?

• Physical model– Common in architecture, engineering

• Virtual model– 1970’s – replicating drafting– 1980’s – more powerful computers,

better displays– Either 2 or 3-D

Modern CAD / CADD

• Full object specifications– Dimensions–Material– Finishes– Dynamic systems (forces)

• Now includes CAM (CNC)– Interfaces to 3-D printing

Google SketchUp

• Free CAD solution• Resources on I:~\Davis\Templates\SRT II\

Google Sketchup Files• Also – YouTube tutorials; free tutorial files
