AUTOCAD COORDINATE SYSTEM

TYPE OF COORDINATE SYSTEM USED IN AUTOCAD

There are three types of coordinates system used in AutoCAD :-

1) Absolute Coordinates System :- 

In this coordinate system all input points specify by standard Cartesian coordinates x and y.

• For using absolute coordinate, enter points by typing x and y coordinate point (x,y).

Using Procedure of Absolute coordinates system :-

First of all choose a command for example
Choose LINE command: L [Enter]
Specify line starting point A: 0,0 [Enter]
Specify line next point B: 2,2 [Enter]
Specify line other next point C: 2,3 [Enter]

Different types of SolidWork Commands

2) Relative Coordinates System :-

• In this if you specify first points then you can specify next points coordinate with compare or relative from the previous points.
• The relative coordinate started with symbol "@" .
• In relative coordinate, specify net point by typing @x,y

Using Procedure of Relative coordinates system :-

First of all choose a command for example
Choose LINE command: L [Enter]
Specify line starting point A: 0,0 [Enter]
Specify line next point B: @2,2 [Enter]
Specify line other next point C: @0,1 [Enter]

3) Polar Coordinates System :-

• This coordinates used when you need to draw the next points at specify angle. 
• It is entered in the form of Distance and Angle.
• It is also started with symbol "@".
• In this specify net point by typing @distance<angle.

Using Procedure of Polar coordinates system :-

First of all choose a command for example
Choose LINE command: L [Enter]
Specify line starting point A: 0,0 [Enter]

Specify line next point B: @2.828<45 [Enter]
Specify line other next point C: @1<90 [Enter]
