INTODUCTION
The word AutoCAD is made up of two words Auto(logo of company) and C
(Computer aided design).
AutoCAD is 2D and 3D modelling software.
It is developed byAutodeskcompany.
Autodesk is an U.S.A. based company.
It is widely used in industry for 2D drawing and 3D modelling.
In another way we can say that AutoCAD is a designing course , which is pe
the help of computer.

Version ofAutoCAD
AuotCAD 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 new version of AutoCAD 2000 after that 2001,
on.
This time ,we have the latest version of AutoCAD is 2015, which is launched
March 2014.
Latest version is easy to use and over come the difficulties of old version.

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) an
4).
There is so many commands like copy , move , rotate , mirror in
, array , rectangular array , polar array & more.
Different type of drawings can be made in the same time by usi
command that is LAYER.
Using line , arc , circle , rectangle , ellipse & polygon , so many
of different type can be made.

Co-Ordinate System Every thing that we draw in AutoCAD is exact.
All object drawn on screen is based on simple XY 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 sh

The UCS and WCS
The AutoCAD world ids 3 dimensional . However , if we want to draw a 2D objec
plan or a section , we will use only 2 Dimensions (X and Y).
WCS (World Co-ordinate System)is the imaginary plane that is parallel to the g
default coordinate system.
Modification made to the World Coordinate System (WCS) result in a User Coor
System (UCS) . It is the plane that you work on . It enables the user to draw 3 d
object.
To create a new UCS ,type ucs on the command window , then say New and sp
on your new UCS plane

Hatching
Hatching is used to add shaded patterns to objects and shapes within an A
drawing . Hatch patterns can be used to indicate a material to be used , suc
concrete hatch.
You will pick :
Pattern
Scale
Angle
Points

3D Modeling
Solids contains the mass properties of 3D objects.
You can use the Solids toolbar for readily accessible objects.
Box
Cylinder
Wedge
Torus
cone
Sphere
You can use these operation for more complicated shapes.
Union (Join two solids )
Subtract (carve out the second solid from the first )
Intersection (only the common areas)

3D commands
Extrude
Extrusions can extend in Z direction to be set to taper or follow the path.
You can extrude an open or closed object to create a 3D surface or solid.
Vscurrent
It is used for setting of view style of diagram , which may be
1. 2D wireframe
2. Realistic
3. 3D hidden

3D commands
Sweep
Creates a solid or surface by sweeping an open or closed , planer or non planer curve
along an open or Closed path
RevolveCreates a solid or surface by REVOLVE an object around an axis .

Use of Extrude command
If you Extrudea surface into the third dimension , you simply add a thicknessi
basically is same as creating a solid object .
