The viewer is positioned such that objects (such as boxes or buildings) are viewed from one corner, so that two sets of horizontals diminish towards vanishing points at the outer edges of the picture plane, while only verticals remain perpendicular.

(a)  

In a full section, the cutting plane line passes fully through the part.

(a)  

The cutting plane line cuts halfway through the part and removes one quarter of the material.

(a)  

The viewer is looking up or down so that the verticals also converge on a vanishing point at the top or bottom of the image.

(a)  

Used to generate a section for a small area without using a cutting plane line.

(a)  

Usually used on symmetrical circular parts.

(a)  

The simplest and easiest type of perspective drawing to produce.

(a)  

only a portion of the drawing is shown in the section, and this detail is removed to the side.

(a)  

Show a cross section of an area turned 90 degrees or perpendicular to the object.
