CEE 498C AutoCAD
Graphics Communication for
Civil and Environmental
Engineers
Introduction to the class and the software
Chapter 1
Goals
1. Provide students with AutoCAD skills
and knowledge of graphics
communication for CEE projects so
that they are able to create
drawings, in an efficient manner,
that convey, with a high level of
clarity and with sufficient detail, a
CEE design to their colleagues.
Goals
2. Provide students with the skills to
3.
4.
use modern computing tools to
facilitate the engineering design
process
Teach the students basic concepts of
requirements for design and
computations of CEE projects
Familiarize the students with CAD
applications in various CEE fields
Class Format - Lectures
• About half the lecture on Mondays
• Discuss basic elements of CEE drawings,
techniques for creating 2D drawings of
3D structures, organization of drawing
packages, etc.
• Discuss fundamental ideas of CAE and
use of CAE in design in certain CEE
applications such as hydrology, roads,
structural drawings.
Class Format - lectures
• Answer questions about skills learned
in the lab
• Provide a very brief discussion of the
upcoming lab - what can you do to
prepare for the lab
• Explore related topics such as
standards, drawing sets, flood planes,
drainage basins, contours, etc.
• Explore BIM concepts and 3D
Class Format - labs
• About half the session on Mondays
and 1.5 hours on Wednesday
• Learn AutoCAD skills
• Independent Study – about 3 hrs. per
week
• Practice AutoCAD skills
• Practice creating a design and communicating
it using 2D drawings
Class Outline & Conduct
• Schedule
• Note midterm exams, missed
classes
• Homework
• Note when a hard and/or a soft
copy of the answers are required
• Late homework?
• Grading policy
Software
• We will start with Autodesk AutoCAD 2013,
for Windows
• AutoCAD is available for Mac, but it lacks
some features of the Windows version. For
more details , visit:
http://www.autodesk.com , support, AutoCAD for Mac.
• This class will use Autodesk AutoCAD 2013.
You can download it for free as a student
from:
http://students.autodesk.com
• The software is also available in More Hall

Technical Drawings and CAD
• Drawings (drafting) Is a drawing technique
that creates accurate representations of
objects in engineering and Science
• Graphic Communication is a method of
communication using technical drawings
• Computer Aided Design (CAD) is the
creation of technical drawings using
software.
Drawing Standards (ISO and ANSI)
• ISO: International Standard Organization
• International System of Units,
abbreviated SI (System Internationale)
• Metric standards (meter, cm, mm, etc.)
• ANSI: American National Standard Institute
Scale
• Representative Fraction (same units)
•
•
1/50 or 1:50
Equivalence relation
1” = 20 ft
Graphical Scale
Scale
Full, Large, and Small Scales
• Full Scale: objects are drawn 1:1 scale
• Small Scale: Objects appear on a drawing
“smaller” than reality:
1:100, 1”= 15’
• Large Scale: Objects appear on a drawing
“Larger” than reality
• NOTE THAT SURVEYORS WILL HAVE A
DIFFERENT INTERPRETATION OF SMALL AND
LARGE SCALES
Scale and CAD
• DRAWINGS IN AUTOCAD ARE AT FULL
SCALE, they are scaled down when you
print.
• AutoCAD comes with a set of
representative factors and
equivlance relations scales
• You can add and delete new
• scales
INTRODUCTION TO THE SOFTWARE
• We will move to the lab in More Hall for hands-on
practice
• Few remarks:
• Almost any command in AutoCAD can be done in
several ways
• Try to get used to type the commands and memorize
the shortcut much as you can. It is easier for
example to type “L” to draw a line than to click on an
icon or select from a drop down menu. Shorcuts are
in the resources
• Section of the website
INTRODUCTION TO THE SOFTWARE
• There are some tricks to make your work more
efficient, such as:
• Shift + right click on the screen, will give you an option
to draw from a point half way between two other
points that are not connected. That is easier than
drawing a line between them and snap to its middle
• While in that mode, if you select to snap to the middle
of a line for example, you will snap only to middle of
lines, handy in busy drawings
• “tk” command, while executing another command and
expecting a point, will let you navigate to a point by
visiting other points, reduces construction lines.
INTRODUCTION TO THE SOFTWARE
• Control +1 will bring up properties pallet of a
selected object such as a circle. You can view and
verify the properties of the object, but you can also
modify the object this way.
• If you want to print a drawing but X and Y, or N and E,
are not along the long and short sides of the paper,
you may need to rotate the drawing so that the Y or
N is tilted WRT to the paper, type UCS, rotate the X
and Y, and type: plan to rotate the map so that the
UCS Y axis is up. That will rotate the drawing. Bring
back the CS to the way it was by clicking on the
arrow under the navigation wheel and select WCS
INTRODUCTION TO THE SOFTWARE
• When you know more about the software,
remember to plan ahead, before you
draw:
• Determine your units
• Decide on a scale and paper size
• Setup your styles: text, dimensions, tables,
etc.
• Difference between classic and drafting & annotation in
AutoCAD, which is better??
