Computer Aided Design and Drafting

• Introduction

2
Objectives

• Upon completion of this lesson you will be able
  to
• Identify and Describe a Technological System
• Identify and Describe components of a computer
  system
• Describe CAD
• Identify and Describe capabilities of a CAD
  system
• Identify and Describe basic functions of CAD
  software

3
Technological System

• Inputs Processes Output
• Feedback

4
Components of a Computer System

• Hardware
• Software

5
Hardware

• Physical components of a computer system
• Examples Monitor, Keyboard, Mouse, Hard drive,
  Motherboard, DVD drive, CD Rom, Flash drive,
  Memory, Video Card

6
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)

7
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)

8
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

9
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

10
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)

11
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)
