A

IGES

41
Q

What are the advantages of CAD?

A
  • Easy to store and retrieve drawings &files
  • easy to modify models and drawings
  • don’t have to redraw repetitive elements using a CAD library
  • drawing speed & quality are improved
  • layout of drawings can be standardised
  • Drawings can be very large and don’t require paper
  • flexibility of only needing a CAD supported device
42
Q

What are the disadvantages of CAD

A
  • The large cost e.g. hardware, specialist software to run the program
  • Additional costs of updating software and maintaining hardware
  • time and cost of training staff to use the software
  • Potential security issues (hackers)
  • Potential IT problems (crashes, viruses etc)

46
Q

What is the function of 2D CAD?

A

Used to create technical drawings of buildings

47
Q

What is the function of 3D CAD

A
