What is Auxiliary views in Engineering, Autocad and 3D Studio Max?

The Views/Section Which Cannot be seen from the Top,Bottom, Right,Left, Front & Back. It always inclined.

Good Answer,  Syed Shan haider.

Auxiliary views shows the true shape / size of a feature or the relation ship of part features that are not parallel to any of the principle planes of projection.

Any view that lies in a projection plane other than the Top (Horizontal), Front (frontal), Side (Profile) plan or a plane parallel to one of these three (Bottom, Back, Opposite side) is called an auxiliary views. This type of projection is essential, if the part to be drawn is parallel and has a verity of lines or surfaces that are not parallel to one of three principle planes.
