        ISOMETRIC PROJECTIONS 
                 LECTURE 4 
    WHAT IS ISOMETRIC DRAWING? 
   It is a method of producing pictorial 
   view of an object showing all three 
   faces of the object simultaneously. 
   
   It is a type of parallel projection. 
   
   It is a type of axonometric 
   projection. 
   
      ISOMETRIC PROJECTIONS 
   Observer is placed at infinity. 
   Projectors parallel to each other and perpendicular to 
   projection plane. 
   Object is inclined with respect to projection plane in order 
   to see all the three faces. 
          ISOMETRIC TERMINOLOGY 
      1.  The  three  coordinate  axes  are 
          called isometric axes. 
      2.  Any  line  parallel  to  isometric 
          axes is called isometric line.  
      3.  A non-isometric line is a line not 
          parallel  to  any  of  the  three 
          isometric axis. 
      4.  In isometric projection of cube, 
          the faces of the cube and any 
          plane parallel to them is called 
          isometric planes.
