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

orthogonal cutting is a 2D cutting having 2 forces i.e cutting force and feed force where as oblique cutting is a 3D cutting having additional force i.e radial or passive force.
1.)Oblique sketch has a more focus on the front side of an object or the face while isometric sketch focuses on the edge of an object. 2.)Oblique sketch drawn usually using the 45-degrees angle to render the third dimensions while isometric sketch drawn using 30 degrees angles.
Oblique is the "three-quarters" angle to any figure. There is the front view, the side view, and the oblique. It is an interesting angle because the shapes in the figure stretch and vary according to the new position of the figure. A good example is to view the hand from the palm and then move the hand thumb up about 30 degrees. Note the difference in the shapes that become apparent. For artists, this is a popular pose for a model because the angles and masses shift with unexpected beauty.

The advantage is that they can give an overall view of a given design The disadvantages are that it can get more cluttered
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.
Isometric, orthographic and oblique drawings.
There are three types of Pictorial Drawing: Isometric Drawing Perspective Drawing Oblique Drawing
A. Axonometric and oblique drawings-three-dimensional drawings constructed without the use of perspective-are gaining popularity because they are quicker and easier to execute, and because their dimensions remain true to scale for any view. Because these views are easy to draw with instruments, they become suitable for use on working drawings.
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.
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.
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'.
With high oblique photographs, you cannot see what is known as "dead ground" (parts of the area that are behind things like buildings and hills) And with low oblique photographs, you cannot see the horizon properly.

A pictorial and schematic drawing show all of the components of a specific system and the wiring between these components. These drawings can be used for assembly or for trouble shooting and repair.
