For this project, my role included reverse-engineering a real toy submarine by carefully measuring its dimensions with calipers and other manual tools, then translating those measurements into a precise CAD model. I replicated the submarine in SolidWorks, using parametric modeling to ensure accuracy, scalability, and ease of modification. Throughout the process, I focused on maintaining dimensional fidelity and capturing the details of each component, from the outer body to the internal features. Once the model was complete, I created assembly relationships and constraints to reflect how the parts fit together in the real submarine. I also produced detailed engineering drawings with annotations and dimensions, ensuring the design was fully documented and could be used for future analysis, replication, or potential manufacturing.
