What is plane of projection in engineering drawing?

Space and Astronomy

Definition of plane of projection : a plane that is intersected by imaginary lines drawn from the eye to every point on the object and that is therefore the plane on which the pictorial representation in perspective is formed.

What are the 3 planes of projection?

Figure 5-4 shows the three principal (or primary) planes of projection, known as the VERTICAL, HORIZONTAL, and PROFILE PLANES. The angles formed between the horizontal and the vertical planes are called the FIRST, SECOND, THIRD, and FOURTH ANGLES, as indicated in the figure.

What is projection projector and plane of projection?

The figure or view formed by joining, in correct sequence, the points at which these lines meet the plane is called the Projection of the object. The lines or rays drawn from the object to the plane are called Projectors. The transparent plane on which the projections are drawn is known as Plane of Projection.

What are the types of plane of projection?

These include the Frontal Plane, Profile Plane, and Horizontal Plane: In addition to this, if a plane is placed at any other place, then it is called Auxiliary Plane. These are used to draw inclined surfaces of an object.

How do you draw a plane projection?

Video quote: So very simple in case of the projection of plane in the first stage you have to assume the plane is either parallel to vp or parallel to hp in the second stage surface is inclined to hp or vp.

What is meant by plane of projection?

Definition of plane of projection



: a plane that is intersected by imaginary lines drawn from the eye to every point on the object and that is therefore the plane on which the pictorial representation in perspective is formed.

What are different types of planes in engineering drawing?

2.1. 1 Reference planes Principal planes – horizontal plane and vertical plane –are the main reference planes used in orthographic projections. Profile plane, auxiliary vertical plane, and auxiliary inclined plane are also used as reference planes when two views of the object are not sufficient.

How many projections Does a plane have?

1. When the plane is perpendicular to any reference plane its projection of plane will appear as a line in the same plane. 2. When the plane is parallel to one reference plane its projection of plane will appear as a true shape in the same plane.

How many planes are there in engineering drawing?

views that are produced by six mutually perpendicular planes of projection. surfaces of the object positioned so that they are parallel to the sides of the box, six sides of the box become projection planes, showing the six views – front, top, left, right, bottom and rear.

What are the 4 standard types of projections?

Projection Methods Used In Mechanical Drawing

  • Orthographic Projection. Orthographic projection shows a 3D object in two dimensions so that you can see three views: the front view, side view and top view. …
  • Axonometric Projection. …
  • Oblique Projection. …
  • Perspective Projection.


What is isometric projection in engineering 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 is isometric plane?

Any line parallel to one of these is called an isometric line. The angles in the isometric projection of the cube are either 120° or 60°, and all are projections of 90° angles. In an isometric projection of a cube, the faces of the cube, and any planes parallel to them, are called isometric planes.

What is 1st angle projection?

In the first angle projection, the object is placed in the 1st quadrant. The object is positioned at the front of a vertical plane and top of the horizontal plane. First angle projection is widely used in India and European countries. The object is placed between the observer and projection planes.

What is 3rd angle projection?

3rd Angle project is where the 3D object is seen to be in the 3rd quadrant. It is positioned below and behind the viewing planes, the planes are transparent, and each view is pulled onto the plane closest to it. The front plane of projection is seen to be between the observer and the object.

What is 2nd angle projection?

For 1st angle projection system, we place object in 1st quadrant, for 2nd angle projection system, we place object in 2nd quadrant and so on. In Second quadrant, Vertical plane (VP) lies in between object and observer.

What is 1st 2nd and 3rd angle projection?

To get the first angle projection, the object is placed in the first quadrant meaning it’s placed between the plane of projection and the observer. For the third angle projection, the object is placed below and behind the viewing planes meaning the plane of projection is between the observer and the object.



Where is 1st angle projection used?

First angle projection is widely used throughout all parts of Europe and often called European projection. Third angle is the system used in North America and alternatively described as American projection.

Why do we use 1st and 3rd angle projection?

We consider that horizontal plane rotates in clockwise direction after having projection on it. that’s why we use 1st angle and 3rd angle projection. because only in this two quadrants we will get the both views after clockwise rotation of horizontal plane.

What is auxiliary plane?

Auxiliary Plane The plane which we draw to get the true shape of the inclined surface ( often parallel to Principal Plane ) is an auxiliary plane. Simply, the plane other than the Principal Plane ( i.e. Horizontal Plane, Vertical Plane or Perpendicular Plane) is called Auxiliary Plane.

Where the plane is placed in third angle projection?

In the third angle projection, the object is placed in the third quadrant. The object is placed behind the vertical planes and bottom of the horizontal plane.



In which angle of projection plane of projection is transparent?

Detailed Solution

First angle projection Third-angle projection
The plane of projection is assumed to be Non-transparent The plane of projection is assumed to be transparent.
Front (elevation) view is drawn above the XY line Front (elevation) view is drawn below the XY line

Which of the below views are 3rd angle of projection?

There are three main views in the third angle projection; Front View. Side View. Plane View.
