Purpose of Assignment #3 The purpose of assignment three was to learn more about assembly documentation. We were assigned to draw a concept sketch for a simple assembly. I personally chose to do a meat tenderizing hammer that I manufactured in my High School career. We also had to produce a set of complete part documentation drawings for each custom part. After that, we had to create an assembly drawing in the exploded isometric format. The assembly drawing had to be complete including balloons to specify each part and a parts list. All of these drawings were to be done by hand.
