  1. Objective: Review and demonstrate understanding of the effects that Computer-Aided Design (CAD) has on every part of the process of design Warm-up • How do Engineers read?

  2. Reading like an Engineer Engineers read back and forth between the text and visual diagrams because the visuals are essential for deep understanding of concepts.  Engineers think critically and visualize while reading about information that is changing from one form to another.  Engineers look for patterns during reading to acquire deeper understanding. Engineers make conjectures during reading to begin creating fresh ideas.  Engineers create questions based on facts and data about what they are observing.  Engineers make predictions based on what they read.  Engineers visualize during reading.  Engineers use imagery during reading to project concepts into their thinking.

  3. CAD Review • Traditional drawing tools include • T-square • Drawing board • Plastic Triangle • The parts of a CAD workstation include: • Computer • Keyboard • Display Screen • Drawing Tablet • Plotter

  4. CAD Review • Traditional drawing methods are used to draw or design: • Portraits • still life and landscape art • Animals and detailed living things • CAD is used to design: • Cars, aircraft, furniture, rugs, and other textiles and electronic games

  5. CAD Review • CAD is an important software application that allows people to produce drawings using a computer instead of traditional drafting tools. • CAD saves time by combining designing and drafting into a single process • When using CAD the SIZE, SHAPE and SCALE of final drawings can be easily modified

  6. Designers can create physical 3-D scale models using 3-D printing machines

  7. Using CAD versus Traditional Drawing Methods Graphic Organizer

  8. Learn to use Sketchup • Logon to your school network account. Go to ‘Angela Bernard’ Hand-Out folder • Go to the Sketchup Folder and complete the 3 tutorials • Save your tutorial designs in your class’ folder in the ‘Angela Bernard’ Hand-In folder. • Include your name and the date in the file name • Example: ‘Bernard Part 1 - 11122012’ • Open a new file in Sketchup and recreate your candy dispenser design • Obtain objects from the 3D Warehouse to represent the parts in your Inventors’ kit. • Save designs in your class’ folder and include your name and the word ‘Dispenser’ in the file name • Example: ‘Bernard Dispenser’ 1ed
