It is a 3D representation in two dimensions. Width and height are drawn on horizontal and vertical lines and depth is on an angled line, usually 30 or 45 degrees.
Drawings in oblique projection in which the vertical plane is parallel to the plane of projection (drawing surface), and all three spatial axes are drawn to the same scale.
Isometric, orthographic and oblique drawings.
There are three types of Pictorial Drawing: Isometric Drawing Perspective Drawing Oblique Drawing
Isometric Drawing: keeps the scale the same along each axis of the drawing, use mostly in engineering. Oblique Drawing: is a type of parallel projection of an object to give it a sort of 3D effect on paper, a much simpler form of drawing.
Oblique drawings are designed to show a three dimensional view of an object. It is a kind of a drawing that shows one face of the object in true shape, but the other faces on a distorted angle. Oblique is not really a '3D' system but a 2 dimensional view of an object with 'forced depth'.
Drawing in "oblique perspective" means drawing in a way the has a slanted perspective to show multiple sides often seen in eastern artwroks of antiquity. This differs from orthographic perspective (IE silhouettes) which were used in many classical Greeks and Roman artworks and point-perspective (IE 20th Century Fox logo) which was popular during the renaissance and after in the west.
One remaining drawing conventions is Oblique drawing - In this convention the angles used are 45 degrees and 90 degrees. The only difference between the two named styles is in the scale of the dimension going away from the viewer. This first example is Cavalier Oblique and shows the full scale (1:1) in the axis Cabinet Oblique' In Cabinet oblique the scale (depth) is halved whilst in Cavalier oblique the depth scale is the same as in the X and Y directions.

Oblique cavalier drawings tend to appear distorted and elongated. They are not considered as true projections despite being dimensionally correct.
