In this unit we expanded and practiced our computer modeling skills. We practiced reading dimensions and worked on translating those dimensions into our model properly. We also assembled all of our parts into one finished model properly so the parts moved and stayed the way they should have. This unit was very helpful in expanding my knowledge and skills in this area.
Train Parts before and after Assembly
1. The drawing consisted of different line conventions because each drawing was different and required different line conventions.
2. Sectional view is important in order to show different side of the model and specific requirements.
3. Auxiliary views are used to show the true size an shape of an object. Specifically angled figures.
4. There are limit dimensions, tolerances that include bilateral and unilateral that are used to identify hole types.
5. We use algebraic equations instead of numerical values when defining dimensions in order to allow different fits for the object. If you have one specific number the objects wouldn't fit.
6. The constraints used in this practice was some of the dimensions had to be slightly different in order to fit the part into the assembly.
7. CAD drawings are more specific and precise compared to free hand sketches where there is plenty of room for human error.
