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 are 3 types of pictorial view?
- perspective.
- isometric.
- oblique.
What are the three main types of pictorial sketching?
- Isometric.
- Oblique.
- Perspective.
What are the different types of pictorial drawing explain each?
Isometric drawing
is the most commonly used method of pictorial drawing. Isometric drawings are built on three lines, called isometric axes. One is drawn vertically and the other two with the 30° set square either side of it. An Isometric drawing is a way of presenting designs in three dimensions (3D).
What are the three types of oblique pictorial drawings?
Oblique drawings include three types: cavalier (true length for all sides); cabinet (true length for front sides but half length for the sides on the top and the slanting side. Cabinet oblique looks more natural), and
general
(3/4 scale for the receding axis, drawn at about 15o with horizontal).
What is a pictorial example?
Pictorial is defined as
something illustrated or expressed in pictures
. If pictures tell a story of the history of a given plot of land, this is an example of a pictorial history. … A news magazine made up entirely of pictures is an example of a pictorial.
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.
What is isometric pictorial?
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 is a pictorial line drawing?
A view of an object (actual or imagined)
as it would be seen by an observer who looks at the object either in a chosen direction or from a selected point of view. Pictorial sketches often are more readily made and more clearly understood than are front, top, and side views of an object.
What is boxing method in drawing?
4.5a Boxing method:
When object contains many non-isometric lines
, it is drawn by the boxing method. When the boxing method is used, the object is enclosed in a rectangular box, which is drawn around it in orthographic projection.
What is a pictorial drawing is used for?
A pictorial sketch represents a 3D object on a 2D sheet of paper by orienting the object so you can see its width, height, and depth in a single view. Pictorial sketches are used frequently during
the ideation phase of engineering design to record ideas quickly and communicate them to others
.
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 opposite of a pictorial drawing?

What are the common types of oblique drawings?
- Cavalier: Angle between projectors and projection plane is 45o. Perpendicular faces are projected at full scale.
- Cabinet: Angle between projectors and projection plane is arctan(2) = 63.4o. Perpendicular faces are projected at 50% scale.
What is a oblique pictorial?
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°.
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.
