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.

        RIBBON / APPLICATION MENU :- COMMAND ENTRY

IT SETS AND CONTROLS THE LIMITS OF THE GRID DISPLAY IN THE CURRENT MODEL OR NAMED LAYOUT. THE FOLLOWING PROMPTS ARE DISPLAYED.


                                                                                                                                                                LOWER-LEFT CORNER:- SPECIFIES THE LOWER-LEFT CORNER FOR THE DRAWING LIMITS.

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.
