AIM:

To Create the geometries from P1 to P2 using all the coordinates system methods.

APPARATUS:

Autocad software

COORDINATES SYSTEMS :

Absolute coordinates
relative rectangular coordinates
relative polar coordinates
direct distance entry

PROCEDURE:

open autocad
QNEW command
as decimal units are used (metric is selected )
template = Acad.dwg
use a wizard
advanced setup
units
decimal ( precision 0.0)
angle
decimal degree
angle measure
east
area = 10 x10

ABSOLUTE COORDINATE SYSTEM :

line command
2,1 ( point a)
8,1 (point b)
8,2 (point c)
3,2 (point d )
3,6 ( point e)
8,6 ( point f)
8,7 (point g )
2,7 ( point h)
