• INTRODUCTION
AUTOCAD IS A COMMERCIAL COMPUTER-AIDED DESIGN AND
DRAFTING SOFTWARE APPLICATION. DEVELOPED AND MARKETED
BY AUTODESK, AUTOCAD WAS FIRST RELEASED IN DECEMBER
1982 AS A DESKTOP APP RUNNING ON MICROCOMPUTERS WITH
INTERNAL GRAPHICS CONTROLLERS.
• THE WORD AUTOCAD IS MADE UP OF TWO WORDS “AUTO
(LOGO OF COMPANY)” AND CAD “(COMPUTER AIDED DESIGN).
• IT IS DEVELOPED BY AUTODESK COMPANY.
• AUTODESK IS AN U.S.A BASED COMPANY.
• IT IS WIDELY USED IN INDUSTRY FOR 2D DRAWING AND 3D
MODELING.
• IN ANOTHER WAY WE CAN SAY THAT AUTOCAD IS A DESIGNING
COURSE, WHICH IS PERFORMED BY THE HELP OF COMPUTER.

4. VERSION OF AUTOCAD
AutoCAD software
was firstly
launched by
Autodesk company
in Dec. 1982
It comes in India
in 1988
The first version of
AutoCAD was R1
after that R2, R3,
R4………. and so
on.
In 2000,
Autodesk
launched a
version of
AutoCAD 2000
after that
2001,2002……..
so on.
Latest version is easy
to use and over come
the difficulties of old
version.

8. HOW AUTOCAD WORKS
There is a co-ordinate system used in AutoCAD.
Every drawing shows its co-ordinate.
In above next slide the line shows its co-ordinate that is (9,6) and (-10,-4)
There is so many commands like copy, move, rotate, mirror in 2D, path array,
rectangular array, polar array & more.
Different type of drawing can be made in the same time by using a command that is
Layer.
Using line, arc, circle, rectangle, ellipse & polygon, so many drawing of different type can
be made.

9. CO-ORDINATE
SYSTEM
• EVERYTHING THAT WE DRAW IN
AUTOCAD IS EXACT.
• ALL OBJECT DRAWN ON SCREEN IS
BASED ON SIMPLE X-Y CO-
ORDINATE SYSTEM.
• IN AUTOCAD IT IS KNOWN AS
WORLD CO-ORDINATE SYSTEM
(WCS).
• WE ARE DRAWING A LINE, SO WE
HAVE TWO POINTS A(-10,-4) AND
B(9,6). AS SHOWN IN FIGURE.

10. THE UCS
AND WCS
There are two coordinate systems in AutoCAD. World
Coordinate System (WCS) and User Coordinate System
(UCS) which define the angle of the XY plane you are working
in. The WCS should always be used to reference geometry to
ensure everything aligns to the center of a file in real-world
location
WCS (world coordinate system) is the imaginary plane that is
parallel to the ground. It is the default coordinate system.
Modification made to the world coordinate system (WCS) result
in a user coordinate system (UCS). It is the plane that you work
on. It enables the user to draw 3 dimensional objects.
To create a new UCS, type ucs on the command window, then
say new and specify 3 points on your new UCS plane.

11. DRAW TOOLBAR AND MODIFY TOOLBAR
Following image shows two very basic tool bar,
these will be heavily used as progress towards
the end of your drawing. We can access these
tool bars under Home tab.
As we move cursor over any tool in the
tool bar a tooltip appears stating the name
of that tool. And if we further wait for
about three seconds, it turns into a brief
description about that particular tool. As
show by following image.

12. ANNOTATION TOOLBAR
AutoCAD provides a whole range of
dimensioning tools which can be used to
quickly dimension any drawing without
the need for measurement. Dimensioning
in AutoCAD is automatic: lines, arrows
and text are all taken care of by the
dimension commands. AutoCAD
dismissions are special blocks which can
easily be edited or erased as necessary.
AutoCAD provides lots of control over the
way dimensions look. Using a system like
text styles, dimensions styles allow you to
design dimensions so that they look just
the way you want them to.
