While there are six (6) possible projections - Front, Back, Top, Bottom, Left, and Right Views. Three of these views can give us a complete representation of a 3D model. Commonly, the Front + Top + Right Side View combination is used. The Back view may be omitted as it is an inverse of the Front other, just like the Top/Bottom views, and Left/Right views. However, if a bottom view has more details than the top view, we can use the Front + Bottom + Right combination (instead of Front + Top + Right), for instance.
