There are many types of pictorial drawings and these include isometric, oblique, axonometric and planometrics and the four drawings figures 164 – 167 illustrate the differences between them. Of these, isometric drawings are the most common.
What is the most frequent use of pictorial drawing?
Pictorial sketches are used frequently during the ideation phase of engineering design to record ideas quickly and communicate them to others . Their similarity to how the object is viewed in the real world makes them useful for communicating engineering designs to nonengineers.
What is the most common type of pictorial?

Isometric drawing is the most commonly used method of pictorial drawing. Isometric drawings are built on three lines, called isometric axes.
What are the three most common types of pictorial drawings?

Is axonometric a pictorial drawing?
Axonometric projection is a type of orthographic projection used for creating a pictorial drawing of an object, where the object is rotated around one or more of its axes to reveal multiple sides.
Is picture plane 2D or 3D?
The Picture Plane is the flat two-dimensional surface on which we draw or project an image in perspective.
What is a multiview sketching?
A multiview drawing is one that shows two or more two-dimensional views of a three-dimensional object . Multiview drawings provide the shape description of an object. When combined with dimensions, multiview drawings serve as the main form of communication between designers and manufacturers.
What is isometric pictorial drawing?
Isometric projection is a method for visually representing three-dimensional objects in two dimensions in technical and engineering drawings. It is an axonometric projection in which the three coordinate axes appear equally foreshortened and the angle between any two of them is 120 degrees.
What are perspective drawings?
Perspective drawing is a technique to create the linear illusion of depth . As objects get further away from the viewer they appear to decrease in size at a constant rate. The box in the sketch below appears solid and three dimensional due to the use of perspective.
Which projection has only one view?
Explanation: Orthographic projection is the representation of two or more views on the mutual perpendicular projection planes. But for oblique projection , the object is viewed in only one view.
What is the purpose of multiview projection?
Multiview projections are used to overcome the weaknesses of 3-D projections . Multiview projections are a collection of flat 2-D drawings of the different sides of an object. Only two forms of orthographic projections are used: first-angle (‘European ISO-E’) and third-angle (‘American ISO-A’).
What is the importance of pictorial drawing?
Pictorial drawing is an essential part of graphic language. It is often used to show exploded views on production and assembly drawings (see Figure 12-1). These views are made to explain the operation of machines and equipment, to illustrate parts lists, and so on.
