An Oblique pictorial starts with a straight-on view of one of the object’s faces, which is often the front face.
Angled, parallel lines are drawn to one side to represent the object’s depth. Common oblique angles include 30°, 45°, and 60°.

There are two types of oblique pictorials: cavalier and cabinet. The difference between the two is based on how the depth of the object is represented.

A general oblique is a type of oblique pictorial that represents an object’s width and height, but the depth can be any size and drawn at any angle.
The idea is to worry about getting the thought down as a sketch not worrying about the depth or angle.

Oblique SketchesStep #1: Create construction box.
Step #2: Use points and construction lines to identify edges that occur on the surface of the box.
Step #3: Trace out the visible edges of the part with thick, dark object lines.
Step #4: Use points and construction lines to identify edges that occur on the surface of the box.
Step #5: Trace out the visible edges of the part with thick, dark object lines.

Tonal Shading
Add tonal shading to two of the three views by drawing parallel lines spaced closely together.
Increase the contrast by cross-hatching the lines on the darkest face.
