A Perspective Image is an image that looks realistic and tends to be almost 3D, there is at least one vanishing point. Think of an image of a road. Notice how the road is large where we stand but gradually gets smaller until we can't see it at all? That's where the vanishing point is.
A Non-perspective image is an image that lacks in a vanishing point and is almost flat.
Perspective Drawing uses observed facts of how objects appear to diminish into the distance in reality. This is a formal way to draw what one sees. The basis of the drawing uses an eye-level line that is usually the same as the horizon. When looking at an object such as a box or building the artist must determine if the object is above, on or below the eye-level line, or perhaps has parts in all three areas. Objects above the line have an imaginary line that continues to the Vanishing Point-an imaginary, but observable- point on the horizon where the object would go if it went to infinity. It stops on the eye-level line; horizon line. Perspective drawing is about drawing through space, and it has to do with the 3 Dimensions of height, width and depth. It is the depth that we are trying to find and draw. As in all visual art, one needs to see samples, not just read about it. There is also 2-point Perspective when a person is viewing an object from its corner. In the example of a box, the vertical corner is drawn closest to the viewer, then the left side is drawn to the left vanishing point, the right side is drawn to the right vanishing point. Vertical lines are arbitrarily drawn to end the sides of the box. Remember, this may take place above, on and below the eye-level line. Perspective drawing was developed by the artist, architect Brunnelleschi in the 1400's. There are visual formulas to determine even spacing that goes back into the distance. Learning perspective will help with drawing reality and also will give more understanding for abstraction.
No, not all drawings are perspective. To draw in persective there is a specific layout, useing the horizon, or a vanishing point,.. basicly giveig the drawing a 3d effect, of depth.
There are three types of Pictorial Drawing: Isometric Drawing Perspective Drawing Oblique Drawing
Isometric, orthographic and oblique drawings.
Linear perspective
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.

To read the piping and fabrication drawings easily and correctly the user must have significant knowledge about how the drawings are prepared, and the perspective in which these drawings can be presented.
A knowlege of perspective and practice.

Isometric, Orthographic and Perspective, but perspective is not required to depict an object.
