3D - 2

Could someone please help me with my Design Tech homework?

1)Explain why using Cartesian coordinates enables CAD users systems to produce more accurate drawings than those produced by hand. 2)what are the two main parts of CAD? 3)Why would it be easy to make two circles exactly the same size using CAD? 4) Monitors, printers, and plotters are all examples of what? 5)List two reasons why engineers and designers use CAD 6)Name at least two common uses of 2D CAD 7)What are three kinds of models in 3D models in CAD? 8)What is the difference between surface models and solid models? 9)What is usually the first CAD step for a mechanical designer? 10)List three reasons why mathematical data created during 3D modeling is very important 11)What necessary documents (beside drawings) can an architectural CAD system create Please help!

1. I only know a few of these: 3)Why would it be easy to make two circles exactly the same size using CAD? You can draw one circle, then "clone" or copy it, and it will be exactly the same as the one you copied 4) Monitors, printers, and plotters are all examples of what? Output devices 6)Name at least two common uses of 2D CAD Blueprints artist's conceptions
