Define the Problem
We were tasked to follow instructions to model and create technical digital drawings for a train in the Autodesk Inventor modeling software program.
Generating Concepts
First I read the dimensions carefully before putting them into the software and actually modeling them to make sure I was creating the right object and shape which was specified. Then I turn the two dimensional dimensions and shapes into three dimensional structures to make the parts.
Develop a Solution
Construct and Test the Prototype
Evaluation
After asking parents and friends I found that no one gave any reason that I should change the train's appearance, which is good positive feedback for my own structure.
Present the Solution
Throughout this project I found that there were a few things in inventor which I did not know how to create, this uncludes the hole on top of the cylindrical part of the base of the train and thr threaded wheel peg, but I did learn how to thread and creat holes in any surface through using internes sources. The only other real challenges in the project was when I had to assemble the parts, but I also learned the correct way to perform a few confusing assembalies through my own experimentation.
In the process of creating the technical drawings I also got a little confused with the quarter, or half section cut. The purpose of sectioning is to show the dimensions of hidden parts, ones which would not be able to be clearly defined otherwise. I did not have to look up how to acheive a half section, but it was still tedious. The axilary view, a view which makes it easier to show the dimensions on an angled surface, also gave me problems, and I did have to research how to properly create one, although I may still not fully understand how they wok in Inventor. The broken view gave me no trouble, and its purpose is to shorten a long object to fit nicely onto a technical drawing sheet, sinc if it is shrunk down instead of cut down then it will be too tiny to dimension or read the dimensions. For hole dimensioninh, their reason for using symbols instead of words for the complex ways of describing a hole is simply becaus you want to save as much space as possible, and writing out something like countersink or counter bore or spot face when there may be hundreds of them on something would be extremely tedious and unnecisary. Finally, tolerances exist because error always happen during the real life manufacturing of a product, so they give a pit of leeway to the builders so that if it isn't perfect it may still be able to be used as long as it doesn't exceed or go under the specified tollerance.
