Create drawing views from a multi-body Fusion design. Select orthographic and isometric views that communicate geometry efficiently. Dimension the 20 mm unit structure without unnecessary duplicate dimensions.
Materials
For the online work: a browser and your engineering notebook. Follow the activity’s materials list for any physical build, and get teacher approval before using equipment.
Plan your time
Suggested work block: 45–60 minutes. Physical builds and projects may span several classes; follow your teacher’s schedule.
Lesson Overview
What You Are Learning
Learning Targets
Create drawing views from a multi-body Fusion design.
Select orthographic and isometric views that communicate geometry efficiently.
Dimension the 20 mm unit structure without unnecessary duplicate dimensions.
Create an exploded view that clearly shows the relationship of the five pieces.
Documentation Workflow
Your drawing should communicate the design to someone who did not create it. Include the complete cube, all five pieces, and enough dimensional information to understand the unit-cube geometry.

Puzzle Cube Challenge
Project Requirements
These requirements apply throughout Lessons 2.10–2.13.
Finished Cube
3 × 3 × 3 Unit Cube
27 total unit cubes.
Each unit cube is exactly 20 mm × 20 mm × 20 mm.
The assembled puzzle must be 60 mm × 60 mm × 60 mm.
The final puzzle contains exactly 5 pieces.
Piece Geometry
Five Connected Pieces
Each piece contains at least 3 unit cubes.
Every piece must be one continuous solid with cubes connected face-to-face.
At least 1 of the 5 pieces must span at least 2 unit cubes in X, Y, and Z.
Pieces may repeat the same shape.
Color & Printing
Plan for Manufacturing
Use five different colors consistently in the sketch, Fusion model, and final printed puzzle.
Each piece must have a practical flat-face orientation that can print without support material.
No additional clearance is required; use the exact 20 mm unit geometry.
Assignment
Create the Technical Drawing and Exploded View
Use the five-body Puzzle Cube model from Lesson 2.11. You will create a Fusion drawing from the design and a separate exploded-view image.
Step-by-Step Instructions
Open the final assembled model: Confirm all five bodies are visible and positioned to form the 60 mm cube before starting the drawing.
Create a drawing from the design: Start a new Fusion drawing using the class sheet size and drawing standard specified by the instructor.
Add an assembled isometric view: Place a clear isometric view of the complete puzzle cube. Choose a scale that makes the model easy to read.
Add assembled orthographic views: Include front, top, and right-side views of the completed cube.
Add all five individual pieces: Place separate views for Piece A, Piece B, Piece C, Piece D, and Piece E. Use orientations that make the geometry of each piece understandable.
Add dimensions: Show the overall 60 mm cube dimensions and enough 20 mm-based dimensions to communicate the unit-cube structure and important steps/extents of the individual pieces. Avoid repeating dimensions that are already obvious from another view.
Check drawing quality: Make sure views do not overlap, dimensions are readable, and every piece can be identified.
Export the technical drawing: Save/export the completed drawing as a PDF using the required filename.
Create the exploded view: Return to the 3D model. Save a copy or make sure you can restore the assembled positions. Use Move/Copy to separate the five bodies outward while keeping their relative orientation understandable.
Capture the exploded view: Create a clean isometric screenshot showing all five separated colored bodies and how they relate to the assembled cube.
Restore the design: Undo the temporary body moves or reopen the original assembled model so your main design remains in its correct assembled position.
Before You Submit
The drawing includes an assembled isometric view.
Front, top, and right orthographic views are included.
All five individual pieces have their own clear views.
Overall and unit-geometry dimensions are readable and useful.
The exploded view clearly separates all five colored pieces.
Your original Fusion model remains assembled after the exploded-view image is created.

Videos for Lesson 2.12
Use these three reference videos while working through your Fusion technical drawing and exploded-view assignment. Pause and replay sections as needed. The lesson instructions and submission checklist still apply.

Submission
What You Will Submit
Technical drawing PDF: assembled isometric, front/top/right orthographic views, all five individual piece views, and required dimensions. Save as LastName_FirstName_2_12_PuzzleCube_Drawing.pdf.
Exploded-view image: clear color-coded exploded isometric showing all five pieces. Save as LastName_FirstName_2_12_Exploded.png.
Drawing standard: The drawing should be readable without opening the original Fusion model. Use clean view placement and only the dimensions needed to communicate the geometry clearly.
