advanced computer modeling: model train
Project 8.1a was to model a miniature train. We were given dimensions and an image to copy and had to do our best to replicate it. We had to CAD nine parts based on these dimensions.
conclusion
1. Why are drawings composed of different line conventions?
Drawings are composed of different line conventions because not all lines are the same.
2. What is the purpose of a sectional view?
The purpose of a sectional view is to allow other engineers or a manufacturing company to see the details of your part that you cannot see from the default engineering drawings.
3. What is the purpose of an auxiliary view?
The purpose of an auxiliary is to show the true dimensions of a part that may be distorted due to orthographic projections.
4. Why are symbols used instead of words to identify hole types?
Symbols are used instead of words to identify hole types because symbols take up less space on a page and are universal throughout the world of engineering no matter what language you speak.
5. What advantage is there using algebraic equations instead of numerical values when defining dimensions on a CAD model?
Using algebraic equations instead of numerical values when defining dimensions on a CAD model allows an engineer or a manufacturer to calculate other dimensions based on the algebraic expression.
6. What three types of constraints can be applied to CAD sketches or models?
The three constraints that can be applied to CAD sketches or models are numerical constraints, geometric constraints, and symmetrical constraints.
7. What advantages do CAD drawings have over paper sketches?
CAD sketches allow you to have more accuracy as well as precision. CAD drawings are easier to read than a hand drawing.
