Creation of geometries by Coordinate system methods using AutoCad
Aim:
AutoCAD is a software program used to design, form, and shape the 2-D and 3-D images using a computer. Here this diagram is drawn using 4 coordinates system namely,
- Absolute coordinate system
- Relative rectangular coordinate system
- Relative polar coordinate system
- Direct distance entry system
Which are explained in detail below
Procedure:
P1
Absolute coordinates system:
In command: press L for LINE
LINE Specify the first point or undo: 2,1
LINE Specify the next point or undo:8,1
LINE Specify the next point or undo]:8,2
LINE Specify the next point or undo]:3,2

LINE Specify the next point or [ close or undo]:8,6
LINE Specify the next point or [ close or undo]:8,7
LINE Specify the next point or [ close or undo]: 2,7
LINE Specify the next point or [ close or undo]: click close to the close the drawing
Relative rectangular coordinate system:
In command: press L for LINE
LINE Specify the first point: 2,1
LINE the next point or undo: @6,0
LINE Specify the next point or undo]: @0,1
LINE Specify the next point or undo]: @-5,0
LINE Specify the next point or [ close or undo]: @0,4
LINE Specify the next point or [ close or undo]: @5,0
LINE Specify the next point or [ close or undo]: @0,1
LINE Specify the next point or [ close or undo]: @-6,0
LINE Specify the next point or [ close or undo]: click close to the close the drawing
Relative polar coordinate system:
In command: press L for LINE
LINE Specify the first point: 2,1
LINE Specify the next point or undo: @6<0
LINE Specify the next point or undo]: @1<90

LINE Specify the next point or [ close or undo]: @5<0
LINE Specify the next point or [ close or undo]: @1<90
LINE Specify the next point or [ close or undo]: @6<180
LINE Specify the next point or [ close or undo]: click close to the close the drawing
Direct distance entry system:
In command: press L for LINE
LINE Specify the first point: 2,1
LINE Specify the next point or undo: 6
LINE Specify the next point or undo]: 1
LINE Specify the next point or undo]: 5
LINE Specify the next point or [ close or undo]: 4
LINE Specify the next point or [ close or undo]: 5
LINE Specify the next point or [ close or undo]: 1
LINE Specify the next point or [ close or undo]: 6
LINE Specify the next point or [ close or undo]: click close to the close the drawing
