This document provides instructions for a practical evaluation in a computer aided design (CAD) class. It details how to start the AutoCAD software, display toolbars, create a new file, and save and exit a drawing. It also includes a results section to label parts of the AutoCAD screen, discussion questions about CAD commands, and a student reflection section.

TITLE : 1. INTRODUCTION TO COMPUTER AIDED DESIGN
2. INTRODUCTION TO AUTOCAD FOR WINDOWS
COURSE LEARNING OUTCOME:
CLO1: Understand the concept of Computer Aided Design (CAD).
CLO2: Use computer aided design to accurately generate technical drawing
using AutoCAD software.
OBJECTIVES: The students should be able to:
1. List computer hardware minimum requirements for Computer Aided
Design (CAD).
2. List out the features and capabilities of AutoCAD package.
3. Start AutoCAD commands using various input devices and how to save
finished drawing and exit from AutoCAD.
THEORY :
Computer Aided Design (CAD) is simply, design and drafting with the aid of a computer.
CAD utilizes a computer system in the design process. A computer system which includes
computer hardware and software packages assist in the design automation.
AutoCAD is one of the computer aided design packages developed by Autodesk Inc. that is
used to produce technical drawings such as machine components, layout plan, electrical
drawings and others.
EQUIPMENT : 1. Desktop Computer/Laptop
2. AutoCAD 2004 Software

3. EC202-Computer Aided Design
PROCEDURE :
1. Identify the system requirements needed to run the AutoCAD program.
 To generate technical drawing using Computer Aided Design, you need to have
the following peripherals as seen in Fig. 1.1 below:
i. Input devices: keyboard, mouse
ii. Processing unit: CPU
iii. Output devices: Printer Plotter
Fig. 1.1
CPU
Mouse
Keyboard
 In order to run the AutoCAD 2004 package, the following computer system
requirements are needed:
i. Autodesk recommends on 800MHz Pentium III or better processor.
ii. At least 256MB of RAM, 1024 x 768 or higher display resolution.
iii. 300MB of available hard disk space.
iv. Microsoft Internet Explorer 6.0 with Service Pack or latest edition.

2. Starting the AutoCAD program
 Select the AutoCAD 2004 option from the Program menu or double click
AutoCAD 2004 icon on the desktop as shown in Fig. 1.2.
Fig. 1.2.Starting up AutoCAD 2004
 Once the program is loaded into memory, the AutoCAD 2004 display screen will
appear as at Fig. 1.3.
3. Getting to know the AutoCAD 2004 screen display.
a. Observe and identify every part of the graphic display.
i. Title Bar
ii. Toolbars -Standard, Draw, Modify, Dimension, Osnap, Object Properties
iii. Status Bar
iv. Command Prompt Area
v. Menu Pull-Down Bar
vi. Drawing Area

4. Getting to know the AutoCAD instructions:
a. Identify the following methods to enter commands.
i. Keyboard
ii. Pull-Down Menu
iii. Toolbar icon
b. Identify the method to cancel command.
5. Displaying Toolbars
The use of toolbars in AutoCAD is almost always quicker than any other methods.
But the toolbars you see in the screen are usually displayed by default but if they are
not already displayed, you can display them by using the TOOLBAR command.

6. EC202-Computer Aided Design
 Select toolbars from the Pull-Down Menu <VIEW> .
Fig. 1.4: Selection <VIEW> toolbars
 A dialogue box as shown below in Fig. 1.5 appears.
Fig. 1.5: Customize Toolbars
 Simply click the small box next to the required toolbars in the toolbar list and
you will notice that the toolbars selected will appear on the screen, only waiting
to be drag/move to the appropriate location of the screen.
 Once you have completed your selection/selections, click the button Close.

6. Creating New File
 Select New from the Pull-down menu <FILE> .
Fig. 1.6: Selection <FILE> New
 A dialogue box will appear as in Fig. 1.7
Fig. 1.7: Selection of <templates> for New Files
 From the Template selection, choose:
(i) ACADiso (if your drawing measurement is in metric)
(ii) ACAD (if your drawing measurement is in imperial/inches)
 Double click your selection or click the selection and click the button Open and a
new Drawing Screen will be displayed.
(For your practical works in this course, you will be using the Metric
measurement. Thus remember that your selection will always be the ACADiso
template.)

7. Save and exit from AutoCAD Drawing.
 Select SAVE or SAVE AS from the pull-down menu <FILE>.
Fig. 1.8: Selection <FILE> Save or Save AS
 Choose your directory and type your desired filename.
 Choose your ‘file of type’ e.g AutoCAD 2004 Drawing (*.dwg) or any other type
of files.
 Click the button Save and you can continue drawing or EXIT the AutoCAD
application.
