AIM: Create a geometeries from P1 to P2 Using all coordinates system methods and we need to use line tool to create the coordinates and circle tool at some locations

Introduction :

All the drawings we are going to do in Coordinate system

In autocad there are 3 types of cordinates system

They are

Absoulte coordibate system
Relative coordinate system (Relative rectangular and Relative polar coordinate system)
Direct distance entry

So the coordinate system is where the numbers are used at a sinle point and geometric points

1. Absoulte coordinate system: In this system all the coordinate are starting from the orgin (0,0) at some diatance can taken as ( x,y)

2. Relative coordinate system: The location of the relative coordinate system is difined from the distance from a refernce point when using this coordinate the first point if always from the origin (0,0)

a) Relative rectangular coordinate system: it is a coodinarte system that specifies each point of the numerical coordinates as long x and y directions in this system the first point always start while using @ like (@x, y)

b) Relative polar coordiate system : In this coordinate system the point is taken from the direction of angle like (1< angle)

3. Direct distance entry: In this system the the point starts from origin and the direction taken from the mouse with a specified value entred.

Coomands used

Line Command (L Enter)

Circle Command (C Enter)

Procedure:

Using Absolute coordinate system

Open the Autocad
Click on new
Enter the Line command (L enter) or use Line in Ribbon or use in line in draw tools
Enter the first point (2,1)
Next the coomand ask the another point
Specify the next point (8,1)
Specify the next point (8,2)
Specify the next point (3,2)
Specify the next point (3,6)
Specify the next point (8,6)
Specify the next point (8,7)
Specify the next point (2,7)
Specify the next point (2,1)
And use close (C Enter)

Result

Usind Relative rectangular Coordinate system

Open new drawing
Enter the line command (L Enter)
Enter the starting point (2,1)
Next command ask the next point
Specify the next point (@6,0)
Specify the next point (@0,1)
Specify the next point (@-5,0)
Specify the next point (@0,4)
Specify the next point (@5,0)
Specify the next point (@0,1)
Specify the next point (@-6,0)
Click on close (C Enter)

Result

Using relative polar coordinate

open new drawing
Enter line command (L Enter)
Specify the starting point (2,1)
Specify the next point (6<0)
Specify the next point (1<90)
Specify the next point (5<180)
Specify the next point (4<90)
Specify the next point (5<0)
Specify the next point (1<90)
Specify the next point (6<180)
So close (C Enter)

Result

So finally the direct distance entry method

Open new drawing
Enter the line command (L Enter)
Specify the first point (2,1)
Specify the next point 6 towards the +ve x-axis
Specify the next point 1 towards the +ve y-axis
Specify the next point 5 towards the -ve x-axis
Specify the next point 4 towards the +ve y-axis
Specify the next point 5 towards the +ve x-axis
Specify the next point 1 towards the +ve y-axis
Specify the next point 6 towards the -ve x-axis
And Close (C Enter)

Result

P-2

A) Using Absolute coordinate system

Open the new drawing
Enter Line command by using (L Enter)
Specify the first point (2,1)
Specify the next point (5,1)
Specify the next point (5,5)
Specify the next point (6,5)
Specify the next point (6,1)
Specify the next point (9,1)
Specify the next point (7,8)
Specify the next point (4,8)
Close the command by using (C Enter)

Result

B) By using Rectangular coordinate system

Open the new drawing
Enter the line command by using (L Enter)
Specify the first point (2,1)
Specify the secong point (@3,0)
Specify the secong point (@0,4)
Specify the secong point (@1,0)
Specify the secong point (@0,-4)
Specify the secong point (@3,0)
Specify the secong point (-2,7)
Specify the secong point (-3,0)
Close the command by using (C Enter)

Result

C) Relative polar coordinate system

Open the new drawing
Enter the line command by using (L Enter)
Specify the first point (2,1)
Specify the next point (3<0)
Specify the next point (4<90)
Specify the next point (1<0)
Specify the next point (4<270)
Specify the next point (3<0)
Specify the next point (7<106)
Specify the next point(3<180)
Close the command by using (C Enter)

Result

D) Direct distance entry method

Open the new drawing
Enter the line command by using (L Enter)
Specify the first point (2,1)
Specify the next point 3 towards the +ve x-axis
Specify the next point 4 towards the +ve y-axis
Specify the next point 1 towards the +ve x-axis
Specify the next point 4 towards the -ve y-axis
Specify the next point 3 towards the +ve x-axis
Specify the next point 7 at an angle of 106 towards the -ve x-axis with +ve y-axis
Specify the next point 3 towards the -ve x-axis
Close the command by using (C Enter)
