Here is my Train Project which was assigned to me by Trains R Us. There was a PLTW worksheet given to us with all the dimensions we needed to construct this train on Autodesk Inventor.
define a problem
generate concepts
I started this project by first of all reading over all the dimensions and making sure I was using the correct material, ABS Plastic. The dimensions were kind of confusing to read at first, but after I got some help from my classmates I figured them out.
develop a solution
construct and test a prototype
Evaluate the solution
Decklan Fischer said that I should put more detail on the wheels.
Present the solution
This has been the most challenging project that I have done so far in my time in the engineering program. I had difficulties with the idw files because the dimensions had a high difficulty to really understand because it didn't give you every single dimension, you had to finish the un-given half. I also had to figure out how to create half, section, broken views and more, which I had not done before. The section view is there so the viewer can see what is happening inside of the object. The auxiliary view is to dimension the views and angles that you can't see from the original home view. A broken view is used so you can dimension long object in a small area of space. Engineers use symbols on idw files so that they don't take up as much space as words and they can describe the situation much better. We need tolerances because nothing is perfect so they allow you to have a little bit of wiggle room but not too much or too little. There was an extra touch of difficulty to the project because I only had help from my classmates, none from my teacher.
