SUMMARY
For my Engineering Design class I worked with a team of 2 others to teardown a drill. While we worked collaboratively for the project, my main responsibilities were the exploded view, function structure analysis, and CAD model.
Within the CAD structure, I was responsible for the internals of the trigger structure and the outer case, which consumed the majority of my time. In addition to this I worked to assemble the full design, and create the digital exploded view. We were able to make the CAD model rotate using mates and worked to create the most photo-realistic design we could!
DESIGN ANALYSIS
I performed the physical teardown of the drill with one other member of my team. From this, I labelled, numbered, and cataloged each piece to prepare to create the exploded view. I wanted to preserve the mechanism flow of the drill in the layout, and placed the pieces to mimic the drill's shape, labelling them digitally.

While my teammates worked on modeling the gears, motor, and chuck, I took on the switch, battery, and outer components. For these, my main focus became obtaining accurate measurements and deciding the most efficient and realistic way of modeling the organic shapes of the drill casing. The casing was by far the most elaborate individual item I have modeled, as I attempted to match the aesthetics and material changes.
In the end, our assembly had over 60 individual components including a spinning chuck and motor.
