3              Methods of Drawing Orthographic Projections




First Angle Projections Method                        Third Angle Projections Method
      Here views are drawn                                  Here views are drawn
        by placing object                                    by placing object
          in 1st Quadrant                                       in 3rd Quadrant.

         OBJECT IS OBSERVED IN THREE DIRECTIONS.
           THE DIRECTIONS SHOULD BE NORMAL
               TO THE RESPECTIVE PLANES.
 AND NOW PROJECT THREE DIFFERENT VIEWS ON THOSE PLANES.
   THESE VEWS ARE FRONT VIEW , TOP VIEW AND SIDE VIEW.

  FRONT VIEW IS A VIEW PROJECTED ON VERTICAL PLANE ( VP )
  TOP VIEW IS A VIEW PROJECTED ON HORIZONTAL PLANE ( HP )
    SIDE VIEW IS A VIEW PROJECTED ON PROFILE PLANE ( PP )
