Why did for this assignment is that I went into Inventor and designed the Trolley you can see with the images down below that there are assemblies, which are basically individual parts that come together to make a assembly the final product. You can see that there are actually three assemblies because there are two sub assemblies that goes into the main assembly to make the trolley. This assignment was a really fun one to make because it was. It was the biggest assignment that I have did during that time of the semester and it was also the hardest assignment, but I did have a lot of fun with it and there are some stuff I would change, but overall, I am satisfied with the results.
