Creation of geometries by Coordinate system methods using AutoCad

Project 1st : Creation of geometries by Coordinate system methods using AutoCad

 

Aim: Create the geometries from P1 to P2 using all the coordinates system methods

Introduction: we Use the Imperial Template and the Decimal Units to draft the features, we use auto cad auto cad 2021, for drafting the drawings,  and Draw the profile and the trusses using any coordinate                             system methods. by using following coordinate systems

     1) Absolute coordinate

     2) Relative Coordinate 

          a) relative rectangular coordinate

          b)  relative polar coordinate 

    3) Direct distance entry 

 

procedure to draft the image/drawing

1) Absolute coordinate system: 

           absolute coordinate system is a command for auto cad software that uses the certesion coordinate system to specify a position in the X and Y direction to locate a point on respective direction for. ex, if you put in command the value of (X,Y) so you got that point 

lets disccus procedure: 

 

2) relative coordinate system: we draw the point or line with respective the last point or line 

  a) Relative rerctangular coordinate: in that we locate point with respects to last point ex ( @2,3) for x and y axis

  b) relative polar coordinate method: in that we also locate or draw angle with respective degree ex. (@25<90) here 25 is distance with 90degree angle

3) direct entery: here we use cursor direction for locate point and directly take respective distance

Result:

1) Absolute Coordinate: 

           this method streight forward than other method and its is coordinate method from origine meanse X and Y (x,y) are always starting from start 

 

2) Relative Coordinate:

           this method base on last refrence point, meance according to last refrence point 

                       (x,y) are from last refrence point 

   a) Relative rerctangular coordinate: in that we locate point with respects to last point ex ( @2,3) for x and y axis

   b) relative polar coordinate method: in that we also locate or draw angle with respective degree ex. (@25<90) here 25 is distance with 90degree angle

 

3) Direct distance entry: 

         it is a simplest method other than two method, it is cursor based method, there we draw the point give directon on cursor and put distance on it
