Auto Cad

                                                 Logo of Auto Cad

Ø Now days it is a most popular graphical oriented designing product.

Ø Basically it was developed by sir auto desk in 1972.

Ø The tool called r7.later Mr John from U.S.A. started a new organisation called auto desk in 1980.hedevoleped a product called auto cad.

Ø The first famous product is auto cad 2000.it’s the first graphical version. With the help of this version we can implement.

v Available versions :-In auto cad we are having so many popular versions they are :

                                      I.          Auto cad 2000

                                    II.          Auto cad 2003

                                  III.          Auto cad 2005

                                  IV.          Auto cad 2006&2007

                                    V.          Auto cad 2010&2012

                                  VI.          Auto cad 2014(windows 8 &above versions.)

     

v Hard ware required:-To install auto cad 2010&2012version we need the following hard ware configuration.

                                    I.          Windows 7 &above OS.

                                  II.          Minimum RAM capacity is 1GB.But recommended 2GB.

                                III.          We need high resolution monitor.

                                IV.          Need of a printer.(optional)

                                  V.          Need p4 or above C.P.U. But recommended dual core and above.

                                VI.          The micro processor speed is not less than 1.2G.HZ.

v  Available designing modes: - Basically we are having designing methods like.

                                                               I.          Menu bar.

                                                             II.          Command bar.

Ø Menu bar: - It is the fully graphical oriented option .By using this option we can design type of diagrams without knowing of any syntax .But it is not suitable for learners .basically it is used by professional.

Ø Command prompt: - This is original concept of auto cad designing .it contains the following methods like:

                                                      I.          Standard designing.

                                                   II.          Polar method.

                                                 III.          Cortegen method.

Ø  Types of commands: - In 2010&above versions the commands are mainly classified into two major categories like:

                                                   I.          Administration command.

                                                II.          Designing & modification command.

Ø Administration commands: -

1.    Units : - With the help of this command we can display deferent designing measurements like:

1.   Metric conversion : -

1 centi meter = 10 milli meters

                                                  1 meter = 100 centimetres

                                                  1 kilo meter = 1000 meters

2. Standard conversions : -

1 foot = 12 inches

1yard = 3 feat

1yard = 36 inches

1 mile = 1760 yards

3. Metric conversions to  standard conversions : -

1 MM = 0.03937 INCHES.

1 CM = 0.39370 INCHES.

1 M = 39.37008 INCHES.

1 M = 3.028084 FEAT.

1 M = 1.09361 YARDS.

1 KM = 1093.6133 YARDS.

1 KM = 0.6213 M.

4.Standard to metric : -

1 INCH = 2.54 CM

1 FOOT = 30.48 CM.

1YARD = 91.44 CM.

1YARD = 0.9144 M.

1MILE = 1609.344 M.

1 MILE = 1.609344 KM.

   Limmax: - By using this command we can identify different screen sizes .The original size is 12, 9 inches .But we can also change the screen size.

   Limits: - It is the alternative command to the limmax. It is used before 2010 versions.

   OS : - (Object snap) By using this command we can select or deselect object properties .They are like:

a)     Endpoint.

b)    Midpoint.

c)    O Centre.

d)    Node.

e)    Quadrant.

f)       Intersection.

g)    Extant ion.

h)    Intersection.

i)        Perpendicular.

j)        Tangent

k)     Nearest.

l)        Apparent intersection.

m)   Parallel.

   OP (Object snap): - With the help of this command we can change the screen settings like back ground colour, text colour, font size, pointer size and others.

v Designing commands : -

Ø Line family : - in this category we are having following commands like:

                                                                                                                                           i.          Line.

                                                                                                                                         ii.          M line.

                                                                                                                                       iii.          PL.

                                                                                                                                       iv.          SPL.

                                                                                                                                         v.          RAY.

                                                                                                                                       vi.          X Line.

   Line : -  With the help of this commend we can draw any type of line diagram .To draw a line we have to specify the following steps like:

a.    Specify starting point.

b.   Specify direction.

c.    Specify length of the line.

   Polar method: - It is one of the oldest technique .In this technique we can draw diagrams depending on given angle.

   Cartegen method: - it is another oldest method .In this method we can design anther horizontal or vertical .Means we have to specify x axis & y axis.

   Mline (ml): - It is a similar to line command with one difference .That is we can generate two lines at a same time to do this concepts we have to specify distance between two lines.

   Spl (smooth poly line): - It allows the designer to draw curved lines at the time of designing. We have to off f8.

   Offset: - It is very use full command .By using this command we can generate duplicate object depends on given distance.

   Trim all: - By u sing this command we can remove UN wanted components.

Ø Text operations: - To implement all types of operations We are having the following commands like:

a.    Text.

b.   ED.

c.    ST.

d.   SC.

e.    Mtext

   Text: - With the help of this command we can enter any type of text information to this concept we have to specify height & distance.

   ED: - By using this command we can modify particular text information.

ü BY double click also we can modify text information.

    SL (SCALE): - By using this command we can change the text size.

   ST (style): - It allows the designer to change the font name.

   Mtext: - It is a extend command of text with the help of this command we can performed all types of operations .Like changing font name font size colour and other effects.

   Hatch: - It is a very useful command by using this command we can fill particular objects sign counter or solid surface.

   Break: - By using this command we can remove specified parts of a diagram.

   Join:  - By using this command we can connect tow different lines into a single line .To use this command the two lines must be in similar direction.

   Extend: - By using this command we can extend particular line diagram into specific location.

   Fillet: - Basically it works under corners means we can convert particular corner into a curve format depends on given radius.

   Chamfer: This is a rivers operation of fillet means we can cut particular corner depends on given line 1 & line 2 distances.

   Arc: - We can design arc related diagrams .We can design arc diagrams in two methods.

a)   Manual.

b)   Centre point specification.
