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
(Google 3Dwarehouse)
• SketchUp Intro
• Follow along – SketchUp Self-paced tutorial
Step 2
• Working with edges – Video 2
• Individually – Work through .spt files 1-3
Assignment 1
• See the handout
Objective
• SWBAT– Identify the uses of CAD software by
building models in Google SketchUp
