Introduction
Define the Problem
In this project, my goal was to model parts of a train on Inventor. I used the dimensions given to me in the packet to model and dimension many different parts. After making the parts, I used them to make a fully assembled toy train.
Generate Concepts
When I first started the project, I made the hardest parts in the beginning. This was to make sure that if I needed help in class, I could get it. For parts like the cow catcher and the train body, I used YouTube tutorials while making them. After knocking those out of the way, I easily made parts like the hitch magnet at home. While modeling the parts, I started off by making a 2D sketch. Then, I used the easiest possible feature to make a part, such as revolving on the stack part.
Develop the Solution
Construct and Test the Prototype
Evaluate the Solution
I asked a few people regarding the appearance of my train. Madison said that everything on my train looked good, besides that the pink linkage pegs don't match the rest. Meghan said my train looked like a sprite can. I liked that comment. Finally, Sammy said that my train looked, "swagging." I am not going to change the color of my linkage pegs because I think that it makes my train stand out.

Present the Solution
During the train project, challenges I faced were cutting the holes in the wheel and creating the whole train body. These tasks were hard at first, but after watching some tutorials and getting help from classmates, I eventually completed the parts. The purpose of a sectional view is to provide a view of an object as if it were cut by a saw. I used a sectional view on the stack part. It helps a reader's ability to visualize a part drawn on paper. An auxiliary view shows a view of an angled surface, such as the view I used in the dimensions of my cow catcher part. In the dimensions of my linkage arm part, I used a broken view. Broken views display an object in a small area, using a large scale. The middle of the linkage arm is long and the same all the way through, so there's no point to show a regular view of it. When we dimension holes, symbols are used instead of words because it is overall more efficient. It saves a lot of room on paper because symbols are smaller than words, and all engineers understand the symbols, so you don't need to write the whole words out. Also, when we dimension parts, we use tolerances. Tolerances are needed to account for the margin of error that there's always going to be when producing a part. I used tolerances in my train body dimensions. Throughout the project, I learned many useful skills on Inventor. I learned how to easily make an exploded view by only clicking a few buttons. Also, I learned how to add a thread on an object like I did on the axle peg. Lastly, building this train made me more confident. If we get assigned another big project like this, I feel like I will do a great job making the parts on Inventor.
