3. Outline for Today Drafting Warm-up (Kahoot… Type of car)
Review of Cube Puzzle Challenge
Develop two solutions as isometric sketches
Start building the presentation
Create a Multi-View Sketch of your best solution
Create a physical model of your solution.

4. Design Brief Problem Statement:
A local office furniture manufacturing company throws away tens of thousands of scrap ¾” hardwood cubes that result from its furniture construction processes. The material is expensive, and the scrap represents a sizeable loss of profit.
Design Statement:
Fine Office Furniture, Inc. would like to return value to its waste product by using it as the raw material for desktop novelty items that will be sold on the showroom floor. Design, build, test, document, and present a three-dimensional puzzle system that is made from the scrap hardwood cubes. The puzzle system must provide an appropriate degree of challenge to a person who is three years of age or older.

5. Criteria The puzzle must be fabricated from 27 – ¾” hardwood cubes.
The puzzle system must contain exactly five puzzle parts.
Each individual puzzle part must consist of at least four, but no more than six hardwood cubes that are permanently attached to each other.
No two puzzle parts can be the same.
The five puzzle parts must assemble to form a 2 ¼” cube.
Some puzzle parts should interlock.

7. Cube Project
Multi-view sketch, fully dimensioned of each of the five puzzle parts in your chosen design (Activity 4.1b Graphical Modeling)
Physical model of your puzzle. (Initial each block) (1/11 – 1/13)
Initial and date each piece
Color/decorate the cube
Statistics related to the solution time of your puzzle as required above.
{Some Inventor Training Activities before the next section} (1/13)
CAD drawings for each part, colored the same as the puzzles you built. (1/15 )
CAD drawing(s) displaying a fully dimensioned multi-view of each puzzle part and two different isometric views of the assembled puzzle. (EC)
Drawing review comments from a classmate.
A written summary of your puzzle test results and a discussion of the validity of your design. Does your design meet the design criteria? Does your design “provide an appropriate degree of challenge to a person who is three years of age or older” (as stated in the design statement)? (1/20)
A discussion of possible changes to your puzzle cube that would improve the design. (1/20)

8. Develop Two Models Isometric Drawings
Create two different puzzle cube designs with 5 parts each. Each part has no fewer than 4 cubes and no more than 6 cubes.
One Easy to solve and the other more difficult.
For each design, neatly sketch and color code an isometric view of each of the five component parts and show how they fit together in the isometric view of the cube.
Choose the best design from the two options. Document the reasons for your choice in your engineering notebook.
Test your designs on

9. 4.1b Graphical Modeling Orthographic
Multi View Model
In your notebook, create a multi-view drawing of each of your five puzzle pieces for the selected design.
Carefully select the best front view and include all object and hidden lines.
Show the minimum number of orthographic projections necessary to fully detail the part.
Do not show the joints between individual wooden cubes.
