Practice making 2D sketches of Multi-Views and Exploited view made from Inventor
Toy Train parts
|
Purpose
To practice assemble pieces together and create a train, then animate it. The animation is the exploded view where we show how the train was assembled. To actually put the train on the tracks was the hardest part of the project. We needed the train to actually sit on the tracks and not be floating. We had to practice using the constraint tool to combine two objects together. In class, we had extra credit to make a video of the train moving on the tracks. When there is an error on one constraint, then it would mess up everything else. By practicing constraining and making train parts is a key to create more complicated things in the future. Conclusion 1.) Why are drawings composed of different line conventions? Technical drawings composed of different line conventions are used as a standard internationally. By utilizing a standard means of lines, any language barriers aren't such an issue. 2.) What is the purpose of sectional view? To avoid hidden lines, and to show the inside view, and last to show the material of which the part is made. 3.) What is the purpose of an auxiliary view? An auxiliary view shows the true size and shape of an inclined plane. 4.) Why are symbols used instead of words to identify hole types? Symbols are used to define the characteristics of the hole, such as the thread, the counter bore, and etc. 5.) What advantage is there to using algebraic equations instead of numerical values when defining the dimensions of a CAD model? Algebraic equations will make to object to change its size easier than numerical value. When you have it in algebraic equations, you just have to change one number one by one and you could get the wrong number easier. 6.) What three types of constraints can be applied to CAD sketches or models? There are geometric constraint, numerical constraint, and symmetrical constraint that can be used to apply. 7.) What advantages do CAD drawings have over paper sketches? CAD sketches are more accurate and precise and they can communicate faster and easier than hand drawn sketches. |
