Toy Train Project
Define a Problem
Our task was to use the given specifications of the toy train parts to recreate them on the computer then put the train together in one assembly. Afterward we have to dimension the parts that we made to show the measurements of the features of each part, and we will create multiple views for the assembly itself.
Generate Concepts
To start with the parts I had read all of the dimensions to try to make sense of it and with each part I worked from the bottom to the top. Some dimensions were a bit tricky to understand like "SR" only because I had no previous knowledge of its meaning. Every other dimension was simple, like placing a circle then trimming it or just a rectangle and extruding it.
Develop a Solution
Construct and Test a Prototype
I was absent from school on Thursday/Friday when/if you were signing rubrics. So here's a picture of the degrees of freedom.
Evaluate the Solution
After showing the train to some of my friends I asked them to give feedback for if I were to redo the train, and below is some of the responses.
- Needs to be color coded
- Some dimension drawings are too confusing
- The shapes look like they are fake?
- The body of the train is too basic and should have more features
Present the Solution
During the course of the project I only had problems with creating the orthographic images because some of the different types of views were confusing to do on the program. As I would try to do something I would stop because it didn't seem right or it didn't specify where to click so I had trouble figuring it out, but it didn't take too long to do that. Also throughout the project I learned how to read dimensions better and think outside the box with them. Another skill I picked up was how to edit the dimension styles of the dimensions on orthographic images . The purpose of a section view is to show what dimensions are inside the shape if they are covered up, or to show the 2D shape of a revolved object. The auxiliary feature is used to look at an angled side of an object from a perpendicular view so you can fully dimension the features of that side. The broken view tool can cut the object into a smaller size and still keep the dimension so you can save space, and it is used for shapes that have a long continuous features. Symbols on holes are used to easily write what a hole is by using a easily readable small symbol instead of long words like counterbore or countersink. Finally, tolerances are used to factor in mistakes because nothing is ever perfect. So engineers place in measurements or dimensions that can slightly change and still have the object be functional.
