THE DRAWING COMMANDS YOU WILL PROBABLY USE THE MOST IN AUTOCAD IS LINE. LINES ARE THE BACKBONE OF AUTOCAD .WITH LINE, YOU CAN CREATE A SERIES OF CONTINUOUS LINE SEGMENT. EACH SEGMENT IS A LINE OBJECT THAT CAN BE EDITED SEPARATELY.

THE FOLLOWING PROMPTS ARE DISPLAYED-

CONTINUE:- CONTINUOUS A LINE FROM THE ENDPOINT OF THE MOST RECENTLY DRAWN LINE.

CLOSE:- ENDS THE LAST LINE SEGMENTS AT THE BEGINNING OF THE FIRST LINE SEGMENT, WHICH IS FROM A CLOSED LOOP OF LINE SEGMENTS. YOU CAN USE CLOSE AFTER YOU HAVE DRAWN A SERIES OF TWO OR MORE SEGMENTS.

UNDO:- ERASES THE MOST RECENT SEGMENT OF A LINE SEQUENCE. USING THIS OPTION MORE THAN ONCE BACKTRACKS THROUGH LINE SEGMENTS IN THE ORDER YOU CREATED THEM.

                                                                         CIRCLE

DRAWING A CIRCLE IN AUTOCAD IS RATHER SIMPLE. THE DEFAULT METHOD FOR DRAWING A CIRCLE IS TO SPECIFY A CENTER POINT AND A RADIUS. YOU CAN ALSO CHOOSE TO CREATE A CIRCLE BASED ON A DIAMETER, CIRCUMFERENCE OR AREA. THE FOLLOWING PROCESS ARE SHOWN HOW TO DRAW CIRCLE IN AUTOCAD. THERE  ARE 6 TYPES OF METHOD IN AUTOCAD TO DRAW CIRCLE.

THE FOLLOWING METHODS ARE DISPLAYED-

1.CENTER RADIUS:- 

DRAW A CIRCLE BASED ON A CENTER POINT AND A RADIUS. DEFINES THE RADIUS OF THE CIRCLE. FOR THIS , YOU ARE REQUIRED TO ENTER A VALUE OR SPECIFY A POINT. 

2.CENTER RADIUS:-  

DRAW A CIRCLE BASED ON A CENTER POINT AND A DIAMETER. DEFINES THE DIAMETER OF THE CIRCLE. ENTER A VALUE  OR SPECIFY A SECOND POINT.       

3.2P (POINT):- 

DRAW A CIRCLE BASED ON TWO END POINTS OF THE DIAMETER.  

4.3P (POINT):-  

DRAW A CIRCLE BASED ON THE THREE POINTS ON THE CIRCUMFERENCE.           

5.TAN, TAN, TAN:-  

CREATES A CIRCLE TANGENT TO THREE OBJECTS.     

6.TTR(TANGENT,TANGENT,RADIUS):-

DRAWS A CIRCLE WITH A SPECIFIED RADIUS TANGENT TO TWO OBJECTS.

SOMETIMES MORE THAN ONE CIRCLE MATCHES THE SPECIFIED CRITERIA. THE PROGRAM DRAWS THE CIRCLE OF THE SPECIFIED RADIUS WHOSE TANGENT POINTS ARE CLOSEST TO SELECTED POINTS.

IT CONTROLS THE DISPLAY AND FORMAT OF COORDINATES AND ANGLES AS WELL AS THE ORIENTATION OF ANGLES. THE FOLLOWING OPTIONS ARE DISPLAYED.

LENGTH:- SPECIFIES THE CURRENT UNIT OF MEASUREMENT AND THE PRECISION FOR THE CURRENT UNITS.

TYPE:- SETS THE CURRENT FORMAT FOR UNITS OF MEASURE. THE VALUES INCLUDE ARCHITECTURAL, DECIMAL, ENGINEERING, FRACTIONAL AND SCIENTIFIC. THE ENGINEERING AND ARCHITECTURAL FORMATS PRODUCE FEET AND INCHES DISPLAYS AND ASSUME THAT EACH DRAWING UNIT REPRESENTS ONE INCH. THE OTHER FORMATS CAN REPRESENT ANY REAL-WORLD UNIT.

PRECISION:- SETS THE NUMBER OF DECIMAL PLACES OR FRACTIONALSIZE DISPLAYED FOR LINER MEASUREMENTS.

ANGLE:- SPECIFIES THE CURRENT ANGLE FORMAT AND PRECISION FOR THE CURRENT ANGLE DISPLAY.

TYPE:- SETS THE CURRENT ANGLE FORMAT.

PRECISION:- SETS THE PRECISION FOR THE CURRENT ANGLE DISPLAY.THE FOLLOWING CONVENTIONS ARE USED FOR THE VARIOUS ANGLE MEASURES; DECIMAL DEGREES APPEAR AS DECIMAL NUMBERS, GRADS APPEAR WITH A LOWERCASE G SUFFIX AND REDIANS APPEAR WITH A LOWER SUFFIX. SURVEYOR'S UNITS SHOW ANGLES AS BEARINGS, USING N OR S FOR NORTH OR SOUTH, DEGREES/MINUTES/SECONDS FOR HOW FAR EAST OR WEST THE ANGLE IS FROM DIRECT NORTH OR SOUTH, AND E OR W FOR EAST OR WEST.IF THE ANGLE IS PRECISELY  NORTH,SOUTH,EAST OR WEST, ONLY THE SINGLE LETTER REPRESENTING THE COMPASS POINT DISPLAYED.

CLOCKWISE:- CALCULATE POSITIVE ANGLES IN CLOCKWISE DIRECTIONS. THE DEFAULT DIRECTION FOR POSITIVE ANGLES IS COUNTERCLOCKWISE. WHEN PROMPTED AN ANGLE, POINT OUT THE DESIRED DIRECTION OR ENTER AN ANGLE REGARDLESS OF THE SETTING SPECIFIED FOR CLOCKWISE.

INSERTION SCALE:- CONTROLS THE UNIT OF MEASUREMENT FOR BLOCKS AND DRAWINGS THAT ARE INSERTED INTO THE CURRENT DRAWING. A BLOCK OR A DRAWING THAT IS CREATED WITH UNITS THAT ARE DIFFERENT FROM THE UNITS SPECIFIED WITH THIS OPTION IS SCALED WHEN INSERTED. THE INSERTION SCALE IS THE RATIO OF THE UNITS USED IN THE SOURCE BLOCK OR DRAWING AND THE UNITS USED IN THE TARGET DRAWING. SELECT UNITLESS OR INSERT THE BLOCK WITHOUT SCALING IT TO ,ATCH THE SPECIFIED UNITS.

SAMPLE OUTPUT:- DISPLAYS AN EXAMPLE OF THE CURRENT SETTINGS FOR UNITS AND ANGLES.

LIGHTING:- CONTROLS THE UNIT MEASUREMENT FOR THE INTENSITY OF PHOTOMETRIC LIGHTS IN THE CURRENT DRAWINGS.

DIRECTION:- 

 DISPLAYS THE DIRECTION CONTROL DIALOG BOX. IT DEFINES THE ANGLE 0 DEGREE AND SPECIFIES THE DIRECTION IN WHICH THE ANGLES ARE MEASURED. 

BASE ANGLE:- SETS THE DIRECTIONS OF THE ZERO ANGLE. THE FOLLOWING OPTIONS AFFECT THE ENTRY OF ANGLES, THE DISPLAY FORMAT, AND THE ENTRY OF POLAR, CYLINDRICAL, AND SPHERICAL  COORDINATES.

EAST/WEST/NORTH/SOUTH:- SPECIFIES THE COMPASS DIRECTION (EAST IS THE DEFAULT).

OTHER:- SPECIFIES A DIRECTION DIFFERENT FROM THE POINT OF COMPASS.

ANGLE:- SPECIFIES A VALUE FOR THE ZERO ANGLE WHEN OTHER IS SELECTED.

PICK AN ANGLE BUTTON:- DEFINES THE ZERO ANGLE IN THE GRAPHICS AREA BASED ON THE ANGLE OF AN IMAGINARY LINE THAT CONNECTS ANY TWO POINTS YOU SPECIFY USING THE POINTING DEVICE.

UPPER RIGHT CORNER:- SPECIFIES A POINT IN THE DRAWING AREA THAT REPRESENTS THE OPPOSITE CORNER OF THE RECTANGULAR LIMITS BOUNDARY. 

ON:- TURNS ON LIMITS CHECKING. WHEN LIMITS CHECKING IS ON, YOU CANNOT ENTER POINTS OUTSIDE THE GRID LIMITS. BECAUSE LIMITS CHECKING TESTS ONLY POINTS THAT YOU ENTER, PORTIONS OF OBJECTS SUCH AS CIRCLES CAN EXTEND OUTSIDE THE GRID LIMITS.

OFF:- TURNS OFF LIMITS CHECKING BUT MAINTAINS THE CURRENT VALUES FOR THE NEXT TIME YOU TURN ON LIMITS CHECKING ON.

USER INTERFACE & COORDINATE SYSTEM & IMPORTANT COMMAND

AUTOCAD USER INTERFACE:-

AUTOCAD USER INTERFACE DETAILS

COORDINATE SYSTEM:-   THERE ARE FOUR(4) TYPES OF

 COORDINATE-SYSTEM- 

                    1. ABSOLUTE COORDINATE SYSTEM,
                   
                    2. RELATIVE RECTANGULAR COORDINATE SYSTEM,

                    3. RELATIVE POLAR COORDINATE SYSTEM,

                    4. DIRECT DISTANCE ENTRY    


1. ABSOLUTE COORDINATE SYSTEM:-

IN THE ABSOLUTE COORDINATE SYSTEM ALL POINTS

ARE MEASURED FROM THE ORIGIN (0,0). THEY ARE 

SUITED TO SITUATIONS WHERE YOU KNOW THE EXACT

X AND Y LOCATION OF THE POINT YOU WANT TO 

PLACE.

TO ENTER AN ABSOLUTE COORDINATE USE THE FORMAT

X,Y WHERE X IS THE DISTANCE AND DIRECTION ALONG THE HORIZONTAL AXIS FROM THE ORIGN (0,0). Y IS THE DISTANCE AND DIRECTION ALONG THE VERTICAL AXIS FROM THE ORIGN (0,0).

2. RELATIVE RECTANGULAR COORDINATE SYSTEM:-

 RELATIVE COORDINATE ENTTRIES ARE

BASED ON THE LAST POINT ENTERED. USE A RELATIVE COORDINATE WHEN
YOU KNOW THE LOCATION OF A POINT
IN RELATION TO THE PREVIOUS POINT.

TO SPECIFY A RELATIVE COORDINATE,
PRECEDE THE COORDINATE WITH THE
'@' SIGN USING THE FORMAT @ X,Y
WHERE @ INDICATES A RELATIVE DIS-
TANCE.

X IS THE POSITIVE OR NEGATIVE
DISTANCE ALONG THE X AXIS FROM THE PREVIOUS POSITION . Y IS THE POSITIVE OR NEGATIVE DISTANCE ALONG THE Y AXIS FROM THE PREVIOUS POINT.


3. RELATIVE POLAR COORDINATE SYSTEM:-

A COMBINATION OF ANGLE AND DISTANCE
INPUT IS CALLED POLAR COORDINATE. YOU
USE POLAR COORDINATE WHEN YOU KNOW
THE ANGLE AND THE DISTANCE FROM ONE POINT TO ANOTHER. IN AUTOCAD ANGLES
ARE POSITIVE (+) WHEN MEASURED
COUNTER-CLOCKWISE AND NEGATIVE (-)
WHEN MEASURED CLOCKWISE.

TO SPECIFY A RELATIVE POLAR COORDINATE,
PRECEDE THE COORDINATE WITH THE '@' SIGN
USING THE FORMAT @L<A. HERE L MEANS LENGTH AND A MEANS ANGLE.

4. DIRECT DISTANCE ENTRY:-

A SIMPLIFIED METHOD OF ENTERING COORDINATES WHEN THE DISTANCE AND DIRECTION FROM THE LAST POINT ARE KNOWN IS CALLED DIRECT DISTANCE ENTRY. IN A NUTSHELL, DIRECT DISTANCE ENTRY ELIMINATES THE NEED FOR MOST KEYBOARD ENTRY OF COORDINATES. DIRECT DISTANCE ENTRY CAN BE USED ANYTIME A COMMAND PROMPTS FOR A POINT

LOCATES THE NEXT POINT AT A SPECIFIED DISTANCE IN THE DIRECTION OF YOUR CURSOR

AT A PROMPT TO LOCATE A POINT, ENTER A NUMERIC VALUE

WITH DIRECT DISTANCE ENTRY, YOU CAN QUICKLY SPECIFY A POINT RELATIVE TO THE LAST POINT YOU ENTERED. AT ANY PROMPT FOR A POINT LOCATION, YOU MOVE THE CURSOR FIRST TO SPECIFY THE DIRECTION, AND THEN ENTER A NUMERIC DISTANCE.

IN THE FOLLOWING EXAMPLE, THE SECOND POINT FOR THE LINE WILL BE LOCATED 5 UNITS TOWARD THE DIRECTION OF THE CURSOR. THE DIRECT DISTANCE THAT YOU ENTER IS MEASURED ALONG THE PATH FROM THE LAST POINT TO THE CURRENT LOCATION OF THE CURSOR. THIS FEATURE IS USUALLY USED WITH ORTHO OR SNAP MODE TURNED ON.

THE BASIC INTRODUCTION OF AUTOCAD

INTRODUCTION:-

HELLO MY FRIENDS..BIJAN HERE. TODAY I TALK ABOUT AUTOCAD. AUTOCAD IS A PRODUCT OF AUTODESK. AUTOCAD 1ST RELEASED DECEMBER 1982. IT IS A VERY FRIENDLY SOFTWARE. FULL FORM OF AUTOCAD IS AUTOMATION COMPUTER AIDED DESIGN AND DRUFTING. AUTOCADD IS THE OLDEST AND THE BEST SOFTWARE FOR DRUFTING.NOW WE CAN NOW CREATE 3D MODEL ALSO BY AUTOCAD. NOW AUTOCAD IS USED FOR ARCHITECTS AND ALL ENGINEERS, LIKE ARCHITECT AND CIVIL NEED AUTOCAD FOR PLANNING, ELEVATION, SECTION ETC., MECANICAL ENGINEERS ALSO USED AUTOCAD FOR MECHANICAL FABRICATION DRAWINGS, ELECTRICAL ENGINEERS ALSO USE AUTOCAD FOR CIRCUID DRAWINGS AND ELECTRICAL LAYOUTS.
