In December, my engineering teacher, Mr. Bradley, brought a model truck from his home and showed it to the whole class. This wasn't just a show-and-tell; he was trying to get us to see how modular and how structurally-smart this particular model truck is, and explained how something like that could be made using the software we had already learned throughout the year up to that point.
Now, with the assignment, Mr. Bradley then made a project for us to do, which was to create a custom add-on for that particular model truck.
For every project that my engineering teacher assigns, he requires that I and other students create a "write-up", otherwise known as the documentation process. I mainly use Google Slides for my documentation, and here's a viewable version of one for this particular project.
