Cavalier and Cabinet oblique sketching are two types of pictorial drawing techniques used in technical drawing. The main difference between the two lies in the angles at which the objects are drawn. In Cavalier oblique sketching, the object is drawn with true dimensions along the horizontal and vertical axes, while in Cabinet oblique sketching, the object is drawn with the depth dimension reduced by half. This results in a more realistic representation of the object in Cabinet oblique sketching compared to Cavalier oblique sketching.
Slanting. A slash (/) is oblique

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

Oblique cavalier projection is used in technical drawing to show an object in three dimensions with one face of the object parallel to the picture plane. This projection allows for a quick and easy representation of the object's form, making it a useful tool for presenting designs and concepts in engineering and architecture.
1) Place the object so that the view with the most detail is parallel to the picture plane, especially if the view consists of arcs and circles. 2) Place the object so that the longest dimension runs horizontally across the sheet. 3) In some cases the above two will conflict, and when this is so, rule #1 has preference as the advantage gained by having the irregular face without distortion is greater than gained by observing rule #2. 4) Decisions about viewing an object in oblique projection should aim to show the object so that its shape is most clearly presented and is conducive to showing its dimensions.

Oblique lines:
Oblique means at an angle.
Slanting. A slash (/) is oblique
oblique rectangular
Oblique means slanted or at an angle.
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.
The inguinal ligament runs deep to the external oblique muscle.
