<P> An exploded - view drawing is a technical drawing of an object that shows the relationship or order of assembly of the various parts . It shows the components of an object slightly separated by distance or suspended in surrounding space in the case of a three - dimensional exploded diagram . An object is represented as if there had been a small controlled explosion emanating from the middle of the object, causing the object's parts to be separated relative distances away from their original locations . </P> <P> An exploded view drawing (EVD) can show the intended assembly of mechanical or other parts . In mechanical systems usually the component closest to the center is assembled first or is the main part in which the other parts get assembled . This drawing can also help to represent disassembly of parts, where the parts on the outside normally get removed first . </P> <P> There have been many standard sizes of paper at different times and in different countries, but today most of the world uses the international standard (A4 and its siblings).
