train project
description
Have you ever ridden on a train or owned a train set? The parts that make up the engine car on a train can vary depending on the make and model; however, all train engine cars have parts that are similar.
Interpreting dimensioned drawings is an important engineering skill. Using drawings to create a computer model of a part is also important. You learned earlier in this course that a sketch is the documentation foundation for related technical work. Communicating this information effectively allows a group of people to function as a design team.
In this project you will further develop your modeling skills and your ability to use a computer as an efficient communication tool. The skills that you learned earlier in this course will be systematically applied to model the eight remaining parts needed for the Miniature Train Assembly. The parts with the dimensions are listed below.

conclusion
Why are drawings composed of different line conventions?
So you know what the purpose of each line is, how it should be drawn/interpreted. I.e. Construction lines, hidden lines,exc...
What is the purpose of a sectional view?
Avoid hidden lines, show inside view, show material its made of.
What is the purpose of an auxiliary view?
Show true size or shape of inclined plane.
Why are symbols used instead of words to identify hole types?
Because symbols can identify the characteristics of hole, in a quick organized fashion.
What advantage is there to using algebraic equations instead of numerical values when defining the dimensions of a CAD model?
It makes it easier when proportioning everything, other wise, if numbers were used, you'd have to proportion it by yourself.
What three types of constraints can be applied to CAD sketches or models?
Geometric, Numerical, Symmetrical constraints.
What advantages do CAD drawings have over paper sketches?
Accuracy.
