Creation of geometries by Coordinate system methods using AutoCad
Q.1 Ans: Aim : Draw the given drawing in autocad as per the given sketch using the line tool and where required use the circular tool.
Sol. 1) Absolute coordinnates system :
In this system the drawing is started from the origin.
First point : (2,1) here x- axis is 2 and y-axis is 1
Second point : (8,2)
Third point : (3,2)
Fourth point : (3,6)
Fifth point : (8,6)
sixeth point : (8,7)
seventh point : (2,7)
last point : close.
Relative coordinate system: Points restected to the last point.
- 2,1 Here x is 2 and y is 1.
- @6,0
- @0,1
- @-5,0
- @0,4
- @5,0
- @0,1
- @-6,0
- close.
Relative polar coordinates : here@6<0 (6 is the distance and 0 is the angle)
- 2,1
- @6<0
- @1<90
- @5<180
- @4<90
- @5<0
- @1<90
- @6<180
- close.
Direct distance entry : here position the cursor and then enter the distance
- 2,1
- set the cursor in the right then enter the distance 6
- set the cursor up the 1
- then to the left n 5
- then again up and distance 4
- then again to the right and 5
- then again up and 1
- then again left and distance 6
- then close.

- cursor to the right then 3
- ortho off then 7<106
- then value 3 cursor to the right
- close.
