COORDINATE SYSTEM

COORDINATE SYSTEM

            A coordinate system is a method of identifying the location of a point.

1.    Absolute coordinate system:

Absolute coordinate system uses X,Y and Z axis to establish a point some distance from a common origin

In AutoCad  syntax for  Absolute coordinate system is <X,Y>

Command : Line

From point     :           1,1

To point          :           4,1

To point          :           4,4

To point          :           1,4

To point          :           1,1

Enter.

2Relative rectangular coordinate system:

In AutoCad use relative coordinate system while we know the location of a point in relation to the previous point.

Syntax for Relative rectangular coordinate system is <@ΔX,ΔY>

@ means “From last point”

ΔX means change in X direction

ΔY means change in Y direction

Command : Line

From point     :           1,1 (p1)

To point          :           @3,0 (p2)

To point          :           @0,3 (p3)

To point          :           @0,-3(p4)

To point          :           @0,-3 (p1)

Enter

Polar coordinate system

            In Polar coordinate system each point on a plane is determined by a distance from a reference point and an angle.

In AutoCad  syntax for  polar  coordinate system is (@Length< angle)

Command : Line

From point     :           1,1 (p1)

To point          :           @3<0 (p2)

To point          :           @3<90 (p3)

To point          :           @3<180(p4)

To point          :           @3<270 (p1)

Enter.
