The course began by tasking us to recreate structures along with their respective 2D drawing blueprints

then challenged us to construct mechanically-viable assemblies grounded upon gear ratio calculations.

The final project prompted us to deconstruct a handheld screwdriver and model its constituent parts and drawings.

All models were made using PTC's Creo Parametric 3D Modeling Software.
