Isometric and Orthographic Sketches

Choosing a Design I chose the design of cube B over A because it was included weird shaped pieces and also had more interlocking places which would make it harder for Someone to solve.

Peer Review Questions Is the chosen front view the BEST front view? . While the view is very good, certain pieces remain almost unseen. This whole making the puzzle slightly more difficult to solve based on the drawing, is enough to generate a solution. Has the designer used the minimum number of orthographic projections needed to represent the part? That is, could fewer orthographic projections be used to adequately represent the part? The designer has the used the minimum number of orthographic projections because while more could be added, 3 for each piece is the lowest amount you can go and still be able to recognize said piece. Are the orthographic views properly shown based on the orientation of the isometric sketch of each piece? The orthographic views are properly shown based on the isometric sketch of the puzzle.

Work Reviewed by: Ryan Zhao Are the orthographic projections properly oriented to each other? The orthographic projections are properly oriented to each other because I can see that it shows top, side, and front view in the same order for all 5 pieces. Are all the object lines shown properly (thick and dark)? . While the lines are thick and dark enough to make out, it could be darker. Are all hidden surfaces represented with a hidden (dashed) line where necessary? Yes, all hidden surfaces are represented by dashed lines on the isometric drawings Work Reviewed by: Ryan Zhao

Conclusion Why is it important to have designs and drawings reviewed by peers? It is important to have designs and drawings reviewed by peers because they may find a better way and help suggest ideas that may make the puzzle more efficient. Peers can also point out your mistakes that maybe you have overlooked and help you correct them.
