1 3D ENGINEERING DRAWINGS TOYING WITH TECHNOLOGY

2 WHY IS DRAWING IMPORTANT? Communication Ideas Parts/Assemblies Dimensions and Units

3 WHY I LIKE DESIGN Engineering without technical theories and equations Creative Enjoyable

4 COMPUTER AIDED DESIGN - SOLIDWORKS

5 STARTING OUT You can’t just jump into creating on the computer…. You have to start by hand!!

6 ENGINEERING PAPER English vs. Metric Units Cartesian vs. Engineering vs. Isometric

7 VISUALIZING IN 3D Take 3 to 5 Duplo Legos and put them together however you like Visualize clear box around your structure Draw each side of the “box” on the box template on your table Fold and tape into box formation Does it resemble actual structure?

8 DRAWINGS AND COMMUNICATION Find someone in the room to trade boxes with Can you build each other’s structure? What was easy about building the new structure? What was difficult about building the new structure? What could have improved your build?

9 ENGINEERS DON’T DRAW ON BOXES Let’s find a way to flatten that box Shade in the following sides on your box with the crayons at your table: Top = red Pick two adjacent sides that also touch the top = Make one blue and one yellow

10 ENGINEERING TECHNICAL DRAWINGS

11 ISOMETRIC VIEWS Drawing looking at corner of “box”, not straight on face

12 A LITTLE GEOMETRY

13 A DRAWING DEMONSTRATION 1 – Draw Side Shape 2 – Project Corners Backward 3 - Draw Back Shape

14 PRACTICE ISOMETRIC DRAWINGS Cube – 5 x 5 x 5 Cube – 8 x 8 x 8 Rectangular Prism – 4 x 3 x 7 Rectangular Prism – 3 x 9 x 3 Triangular Prism - Right triangle with legs = 7, depth = 3 Pyramid – Base = 4 squares Cut-Off Pyramid – Base = 16 squares, top row = 4 squares Challenge: Cube 2 x 2 x 2 with pyramid on top

15 FINISH THAT TECHNICAL DRAWING Draw your Duplo Masterpiece on the isometric view of your technical drawing

16 LET’S TRADE AGAIN Find someone new and trade again Build their structure Was one drawing type easier than the other?

17 TECHNICAL DRAWING SYMBOLS Understanding Symbols: online.com/Objects/ViewObject.aspx?ID=ENG16204http://www.wisc- online.com/Objects/ViewObject.aspx?ID=ENG16204

18 TECHNICAL DRAWING LINES Understanding Lines: online.com/Objects/ViewObject.aspx?ID=ENG16004http://www.wisc- online.com/Objects/ViewObject.aspx?ID=ENG16004

19 TECHNICAL DRAWING DIMENSIONS Understanding dimensions: online.com/Objects/ViewObject.aspx?ID=ENG16104http://www.wisc- online.com/Objects/ViewObject.aspx?ID=ENG16104

20 A LITTLE EXTRA VISUALIZATION

21 CHALLENGE BUILD

22 WHY THIS IS IMPORTANT TO YOU Improve accuracy Future Projects Rube Goldberg Boat Activity Lego Egg Drop

23 ASSIGNMENT Draw an item in your kitchen. Under the assignments tab Will turn in by hand Due: September 17th
