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

Some 2D commands

Chamfer Fillet

Copy Mirror

2D commands

SCALEArray

Extend Join


12/22

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)

Some 3D Object

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


16/22

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 .


17/22

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 .
