How to use different types of co-ordinate systems in AutoCAD

There are three types of coordinate systems in AutoCAD and they are explained as follows:

1. Absolute coordinate system: 

Procedure:

1.      Open AutoCAD software and open a new drawing

2.      Set the limits and units

3.      Type L at command window and press enter __|

4.     Specify the first point: type 0,0 at command prompt and press enter __|

5.     Specify the next point: Specify the next point at 0,100 and press enter __|

6.     Specify the next point: Specify the next point at 200,100 and press enter __|

7.     Specify the next point: Specify the next point at 200,200 and press enter __|

8.     Specify the next point: Specify the next point at 350,300 and press enter __|

9.     Specify the next point: Specify the next point at 500,300 and press enter __|

10. Specify the next point: Specify the next point at 500,0 and press enter __|

11. Specify the next point or close: Specify the close option or specify the next point at 0,0 and press enter __|

12. Select Circle command or C __|

13. Specify the center point: Specify the center point at 350,200 press enter __|

14. Specify the radius or diameter for the circle: type 50 as radius for circle at command prompt and press __|

15. Save the drawing with proper file. 

2. Relative coordinate system: 

Procedure:

1.      Open AutoCAD software and open a new drawing

2.      Set the limits and units

3.      Type L at command window and press enter __|

4.     Specify the first point: type 0,0 at command prompt and press enter __|

5.     Specify the next point: Specify the next point at @400,0 and press enter __|

6.     Specify the next point: Specify the next point at @0,100 and press enter __|

7.     Specify the next point: Specify the next point at @-100,0 and press enter __|

8.     Specify the next point: Specify the next point at @100,100 and press enter __|

9.     Specify the next point: Specify the next point at @0,200 and press enter __|

10. Specify the next point: Specify the next point at @-100,0 and press enter __|

11. Specify the next point: Specify the next point at @-100,-100 and press enter __|

12. Specify the next point: Specify the next point at @-100,100 and press enter __|

13. Specify the next point: Specify the next point at @-100,0 and press enter __|

14. Specify the next point: Specify the next point at @0,-200 and press enter __|

15. Specify the next point: Specify the next point at @-100,-100 and press enter __|

16. Specify the next point: Specify the next point at @-100,0 and press enter __|

17. Specify the next point or close: Select the close option or specify the next point at @0,-100 and press enter key.

 18.  Save the drawing with proper file. 

3. Polar coordinate system:

Procedure:

1.      Open AutoCAD software and open a new drawing

2.      Type L at command window and press enter __|

3.     Specify the first point: Click anywhere in the drawing area.

4.     Specify the next point: Specify the next point at @500<135 and press enter __|

5.     Specify the next point: Specify the next point at @500<45 and press enter __|

6.     Specify the next point: Specify the next point at @500<135 and press enter __|

7.     Specify the next point: Specify the next point at @500<45 and press enter __|

8.     Specify the next point: Specify the next point at @500<-45 and press enter __|

9.     Specify the next point: Specify the next point at @500<45 and press enter __|

10. Specify the next point: Specify the next point at @500<-45 and press enter __|

11. Specify the next point: Specify the next point at @500<225 and press enter __|

12. Specify the next point: Specify the next point at @500<-45 and press enter __|

13. Specify the next point: Specify the next point at @500<225 and press enter __|

14. Specify the next point: Specify the next point at @500<135 and press enter __|

15. Specify the next point or cloase: Select the close option and save the drawing.
