Auto CAD
AutoCAD
Auto- Itself or Automatically.
CAD- Computer Aided Drafting and Designing.
AutoCAD is introduced by the company AUTODESK INC.,
In the year 1982.
AutoCAD is the technical software package, which is developed by Americans.
AutoCAD secondary file name or extension (path) file name: *.dwg.
(Dwg is drawing).
It is mainly used in the fields are:
Architectural,
Civil,
Mechanical,
Electrical and Electronics,
Scientific,
Tools designing,
Interiors,
Floorings and any other constructions.
Advantages of AutoCAD:
1) Drawing can be prepared more quickly and accurately with CAD than with traditional methods.
2) Reduction of drafting labor.
3) Reduction in turnaround time.
4) Direct cost saving.
5) High accuracy.
6) Number of Original Print outs
7) Long and Compact Storage
8) Easy Modifications
CAD is the basic technical software package before learning
Catiya, Pro-E, Master-Cam, Micro station version and Archie-cad.
In AutoCAD previous versions like: AutoCAD 2009, 2010, 2011,2012,2013,2014.
In market AutoCAD-2014 is the Latest.
Starting AutoCAD:
Start
Programs
Autodesk
AutoCAD-2010
AutoCAD-2010. (Click or enter).
(Or)
If AutoCAD-2010 icon is available on desktop make a double click on it.
When we are starting AutoCAD we get a "startup" dialogue box on that
We have 4 options
1) Open a drawing : To see the previous saved files directly
2) Start from scratch : To create a new drawing
3) Use a Template : To insert the default template browses
4) Use a Wizard : To create a new drawing like start from scratch
Select (click) Start from scratch
Default settings:
1) Imperial (feet and inches)
2) Metric
Select (click) Metric.
Then we are entered to the AutoCAD classic window:
On that 1) Title Bar: ((AutoCAD-2010 (Drawing1.dwg) with minimize maximize close Buttons.)
2) Menu Bar: ((file, edit, view, - - - - - - help.) with drawing work sheet & minimize maximize close Buttons.)
3) Several Tool bars
4) Command Bar
5) Drawing area or Working area (black color screen)
6) Status Bar: (snap, grid, ortho - - - - - Model)
In this class window drawing area is the major part of the window
By default cursor with pick box and ucs-icon are placed on the drawing area.
Ucs-user co-ordinates(x, y) system.
In AutoCAD we are using 2d and Basic 3d.
When we are start AutoCAD we get 2d default
Start 2d:
2dà 2 dimensional or directional.
In this x, y axis is used.
X-Length(right)
Y-width (height or top)
2d is the top view is of any object.
Screen setup (Paper settings):
Screen setup is the most important before do any drawing.
This setup is depending on 4 basic commands.
All are depending on Commands in AutoCAD:
Commands:
1) Units:
Units enter (type on command line)
We get drawing units box on that do some changes
Length type = Decimal (or) Architectural Angle type=decimal degrees
Precision = 0 (or) 0’-0” Precision = 0

Lighting:
International
Click ok.
2) Limits:
Type on command line Limits enter
0, 0 enter (lower left corner)
100,100 enter (upper right corner).
3) Grid:
Grid enter 10 enter
10 is the spacing between any 2 co-ordinates.
F7 is the toggle key to on/off grid.
By default grid will not displayed beyond limits.
Ds enter or Right click on the grid (Status bar)
We get Draft Settings:
Remove the tick mark on
Display grid beyond limits in Grid Behavior box.
4) Zoom:
Zoom enter all enter
These all are changed as per drawing requirements.
Draw tool Bar:
Creates a straight line segments in any direction.
Line is depending on ortho mode.
Ortho is on: If ortho is on the line moves in straight angle directions
Like (0, 90,180,270 directions).
