hardware
Hardware
  • Physical components of a computer system
  • Examples: Monitor, Keyboard, Mouse, Hard drive, Motherboard, DVD drive, CD Rom, Flash drive, Memory, Video Card
software
Software
  • Application Program
    • Tools that help you accomplish your work:

(designing, drafting, rendering, word processing, Ex: AutoCAD LT 2005, Microsoft Word)

  • System Software (Operating System)
    • Platform to run application programs:

(Windows XP,Vista, MAC OS X)

what is cad
What is CAD?
  • An electronic tool that enables you to make quick and accurate drawings with the use of the computer.
  • CAD is an acronym for:-Computer Aided Drafting-Computer Aided Design-Computer Aided Drafting and Design (CADD)
capabilities of a cad system
Capabilities of a CAD system
  • Flexibility of editing- ability to make quick alterations to a drawing
  • Units and Accuracy levels- ability to change and work with different units and create highly accurate drawings
  • Storage and Access for drawings- save space, quick access, more organized
capabilities continued
Capabilities (continued)
  • Sharing CADD drawings- electronic files can be transferred easily and quickly from any location
  • Design- Allows you to quickly change current designs with accuracy
main functions of all cad systems
Main functions of all CAD systems
  • Draw-
    • add geometry to drawing (lines, arcs, circles, ellipses, text)
  • Edit-
    • change elements of drawings (erase, move, array, copy, offset)
  • Data Output-
    • view/display functions, printing (zoom, pan, scale, colors)
functions continued
Functions (continued)
  • System Control-
    • Setting drawing environment (layers, line types, styles, drawing space, drawing aids)
  • Data Storage and Management-
    • Filing, Saving drawings (open, saving, copying, deleting files)
