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

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.

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

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

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

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