WHY IS DRAWING IMPORTANT?• Communication• Ideas• Parts/Assemblies• Dimensions and Units
WHY I LIKE DESIGN• Engineering without technical theories and equations• Creative• Enjoyable
COMPUTER AIDED DESIGN - SOLIDWORKS
STARTING OUT• You can’t just jump into creating on the computer….• You have to start by hand!!
ENGINEERING PAPER• English vs. Metric Units• Cartesian vs. Engineering vs. Isometric
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?
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?
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
ENGINEERING TECHNICAL DRAWINGS
ISOMETRIC VIEWS• Drawing
looking at corner of “box”, not straight on face

A DRAWING DEMONSTRATION1 – Draw Side Shape2 – Project Corners Backward3 - Draw Back Shapehttp://www.youtube.com/watch?v=ZBuhGaGPYfQ
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
FINISH THAT TECHNICAL DRAWINGDraw your Duplo Masterpiece on the isometric view of your
technical drawing
LET’S TRADE AGAIN• Find someone new and trade again• Build their structure
• Was one drawing type easier than the other?

CHALLENGE BUILD
WHY THIS IS IMPORTANT TO YOU• Improve accuracy• Future Projects• Rube Goldberg• Boat Activity• Lego Egg Drop
ASSIGNMENT• Draw an item in your
kitchen.• Under the assignments
tab• Will turn in by hand• Due: September 17th
