1. 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 System Software (Operating System)
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)
