Creation of geometries by Coordinate system methods using AutoCad

Aim :- To draft the given geometry in AutoCAD by using different coordinate system

Use all the coordinate system to draft the P1 and P2 geometry

Use any one of the coordinate system to draft the remaining geometry 

 

Introduction:-

Coordinate system 

• Coordinate system is a system used to determine the position of the points by using numbers
• Coordinate system may be 2D or 3D coordinate system
• If it's 2D it contains x and y directions (0,0)
• If it's 3D it contains x, y and z directions(0,0,0)

 There are different types of coordinate system

        1. Absolute coordinate system 

        2. Relative coordinate system

           a) Relative rectangular coordinate

           b) Relative polar coordinate

        3. Direct distance entry method

 

1. Absolute coordinate system

• In this system the x and y axis points are mentioned at some distance with respect to the origin (0,0)
• Here x and y represents the distance

2. Relative coordinate system

• In this system the first point of x and y axis is absolute at every time (0,0) and then after the first point all the next points should be with respect to their previous point
• Here x and y represents the distance with respect to previous point

a) Relative rectangular coordinate system

• In this system the coordinates specify each points by using a pair of numbers in x and y axis
• Here the starting pair of numbers is in absolute method (0,0) and the next points should be with respect to previous point
• In command line the relative rectangular coordinate system format should be in @x,y
• Here x and y represents the distance with respect to previous point

b) Relative polar coordinate system

• In this system the coordinate specifies the  distance and angle of the point with respect to the previous point
• Here the starting point is in absolute method (0,0) and the next points should be with respect to previous point
• In command line the relative polar coordinate system format should be in @x<y
• Here x represents distance and y represents the angle with respect to previous point

3. Direct distance entry method

• This method is used to draw the different shapes of geometries in AutoCAD
• This method is helps the user to draw the geometry by simply moving or pointing the cursor in any direction 
• While moving or pointing the cursor in any direction enter the required distance in the command bar 

 

Procedure:-

• Go to start menu, click on Start drawing
• Type stratup (Enter) in command line 
• Enter the new value of start up:1
• Go to application menu and select new or type new in command line
• In the "create new drawing" dialogue box contains imperial  type of systems and metric type of system 
• We select the imperial system in the "start from scratch" option
• After that in Advance setup option select the decimal unit system in the units 

The above procedure should be followed every time when the new sheet is opened
