The lines have an important role in any type of drawing .There are many types
of methods available for drawing lines in an auto cad. Generally three types of
methods are used for drawing in an auto cad.

ABSOLUTE COORDINATES METHOD
RELATIVE COORDINATE METHOD
POLAR METHOD
A. ABSOLUTE COORDINATES METHOD :- In absolute coordinates method.
The coordinates are drawn with the reference of origin.Or the value of
coordinate at the origin point should be zero. Here ABCD is a point and its
coordinate at the origin point should be zero. Here ABCD is a point and its
absolute coordinates are given below.
Important setting in auto cad before line draw
Type the command UCS icon, Select origin.Check the origin coordinate.
B. RELATIVE COORDINATE METHOD :-In this method the coordinates of

coordinate by pointer then OK.
Type the command UCS icon, Select origin.Check the origin coordinate.
In command type line , prompt LINE specify first point type 10,10 then enter
Line specify next point, write coordinate of B point (10,50) then enter.
Line specify next point, write coordinate of C point (50,50) then enter.
Line specify next point, write coordinate of D point (50,10) then enter.
Line specify next point, write coordinate of A point (10,10) then enter.
OR write C enter
B. RELATIVE COORDINATE METHOD :-In this method the coordinates of
forward point are calculated reference to the previous point.
Process :- command line prompt LINE specify first point , type 10,10 then
enter
enter
Line specify next point, write relative coordinate of B point @ 0,40 then enter.
Line specify next point, write relative coordinate of C point @ 40,0 then enter.
Line specify next point, write relative coordinate of D point @ 0,-40 then enter.
Line specify next point, write relative coordinate of A point @ -40,0 then enter.
C. POLAR METHOD:- In the polar method the lines are drawn using angles
and distance. C. POLAR METHOD:- In the polar method the lines are drawn using angles

coordinate by pointer then OK.
In the auto cad measure of angle from east , then the angle of east is 0d or 360d and measured in anticlockwise direction.
In auto cad type command in line
Line specify first point , left click on A
Line specify next point for line AB write : 30<90d then enter
Line specify next point for line BC write : 30<0d then enter
Line specify next point for line CD write : 30<270d then enter
Line specify next point for line DA write : 30<180d then enter
