COORDINATE SYSTEM

1) Absolute Coordinate System: here all coordinates

are measured with origin as a base pointSyntax: x,y x1,y1

2) Relative Coordinate System: here, all coordinates

are measured with the last point as base point

a) Relative Displacement: here, coordinates are

measured from the last point in terms of x and y

displacement

Syntax: @x, y

b) Relative Polar: here, coordinates are measured

from the last point in terms of the distance

(radius vector) and angle of deflection

Syntax: @r

1. start run command2. C:\WINDOWS\DESKTOP> CD ..

3. C:\WINDOWS> CD TEMP

Editing with grips:

Is enabled when the objects are selected using a mouse

without giving any command.

Blue grips: ordinary grips

Red grips: hot grips

Here, we can use 5 editing commands like stretch,

move, scale, rotate and mirror, where copy command

is available in any of the other 5 commands.

Print (plot):

1) Plot device: a printer connected to thecomputer/network is to be specified.

2) Paper size: a paper size on which the drawing is

to be printed is defined.

3) Drawing orientation: landscape and portrait

4) Plot area:

a) Limits: drawing is printed as per the limits

defined.

b) Extent: drawing is printed with exactly

fitting on the specified paper.

c) Display: drawing is printed as per displayed

on the screen.

d) Window: drawing is printed as per the

window selection.5) scaled to fit:

This option automatically adjusts the scale factor

the drawing according to the paper size, orientation

and plot area.

For instance A4 paper size dimension is 8.5X11. If

a user wants to print a drawing in a scale of 1:8(96), then the maximum area that he can print can

be calculated as:

8.5 X 8 = 68 wide

11 X 8 = 88 long i.e. 68 X 88
