AutoCAD is a computer-aided design software developed by Autodesk, first released in December 1982, that supports 2D and 3D design and drafting. The latest version is AutoCAD 2018, which improves user experience and includes commands for versatile drawing techniques. Key features include various coordinate systems, 2D and 3D modeling commands, and benefits such as quick design creation and improved accuracy over manual drafting.

INTRODUCTION

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.
• This time, we have the latest version of AutoCAD is 2018.
• Latest version is easy to use and over come the difficulties of old
version.

3.BY PULLDOWN MENUS

7. HOW AutoCAD WORKS ?
 AutoCAD works on co-ordinate system.
 Every thing 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).
 There is so many commands like copy, move ,rotate ,mirror in 2D,
path array , rectangular array, polar array & more.
 Using line , arc , circle , rectangle , ellipse & polygon , so many
drawing of different type can be made.

8. • Absolute Coordinate System = exact x,y position on the screen.
• Relative Coordinate System = movinng from a known position @x,y to
the new position.
• Polar Coordinate system = moving from a known position @distance <
theta (θ) to new position.
• References= Using ortho, polar, osnap, otrak, grid, snap, infer etc
INPUT METHODS

9. The UCS and WCS
• The AutoCAD world is 3 dimensional. However, if we want to draw a 2d object, such as a
plan or a section, we will use only 2 dimensions (x and y).
• WCS (world coordinate system) is the imaginary plane that is parallel to the ground. It is
the default coordinate system.
• Modifications 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.

10. Some 2D Commands
Chamfer 2. Fillet
Copy 4. Mirror

11. 2D Commands
Scale 2. Array
Extend 4.Join

12. Hatching
• Hatching is used to add shaded patterns to objects and shapes within an
Autocad drawing. Hatch patterns can be used to indicate a material to be
used, such as a concrete hatch.
• You will pick:
– Pattern
– Scale
– Angle
– points

13. 3D Modeling

14. Some 3D Object

15. 3D Commands
EXTRUDE
Extrusions can extend in the Z direction or be set to taper or follow a path.
You can extrude an open or closed object to create a 3D surface or solid.
SHADEMODE
It is used for setting of view style of diagram, which may be…..
1.2D wireframe.
2.Realistic.
3.3D Hidden.

16. 3D Commands
REVOLVE
Creates a 3D solid or surface by REVOLVE an object around an axis.
SWEEP
Creates A solid or surface by sweeping an open or closed, planar or
non-planar curve (profile) along an open or closed path. Open curves create
surfaces and closed curves create solids or surfaces.

17. Use of Extrude Command
• If you “Extrude” a surface into the third dimension, you simply add a
thickness in section. This basically is same as creating a “solid” object .
Extrude 5
units 5 units
Extrude -4
units
4 units
