                     HOW TO DRAW LINE IN AUTO CAD


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
absolute coordinates are given below.

     Important setting in auto cad before line draw
    Open the auto cad drawing sheet.

    •  In Command write Drafting Setting> enter ,




    Open a drafting setting dialog box , left click dynamic input in pointer input.
    Left click on setting changed the mark Cartesian format and absolute
    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

    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. 

      Open a drafting setting dialog box ,left click dynamic input in pointer input.
      Left click on setting changed the mark POLAR format and RELATIVE
      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.

      LINE
      DISTANCE
      ANGLE
      AB
      30
      90d
      BC
      30
      0d
      CD
      30
      270d
      DA
      30
      180d

      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
