First of all, we use first angle and third angle projection because it is assumed that the Horizontal plane is rotated CLOCKWISE to bring them in the same plane (for drawing purpose) and if we use second or fourth angle projection , then the Horizontal and vertical views will overlap , creating confusions in their drawn views. So, we go for third and first angle projection.

To apply the principle of First Angle Orthographic Projection to engineering drawing problems. The definition Orthographic projection is a method of producing a number of separate two-dimensional inter-related views. These views are drawn mutually at right angle to each other. In engineering practice, orthographic projection is universally used to represent solid objects by two dimensional
First-angle projection (European Standards) In first-angle projection, the object is conceptually located in quadrant I, i.e. it floats above and before the viewing planes, the planes are opaque, and each view is pushed through the object onto the plane furthest from it.
In first angle projection, the front view is placed onto first quadrant; top and side view are placed onto the forth and second quadrants, respectively. In the third angle projection, the third quadrant is used for front view; whereas top and side view are placed onto the second and forth quadrants.
In technical drawing and computer graphics, a multiview projection is a technique of illustration by which a standardized series of orthographic two-dimensional pictures is constructed to represent the form of a three-dimensional object.
In first angle of projection plane of projection is taken solid while in third angle of projection it is taken as transparent. Views Sequence In first angle projection right view come in left of front view and top view come at the bottom of front view while in third angle projection right view come on right side of front view and top view comes at the top of front view.
Third Angle projection is a method of orthographic projection which is a technique in portraying a 3D design using a series of 2D views. An alternative method to Third Angle Projection is First Angle Projection.

Chapter 4 Orthographic Projection and Multiview Constructions
Orthographic projections are among the most commonly used in the engineering industry to represent 3D components, structures and spaces in 2d. This film demonstrates how to construct a simple plan, elevation and end views in Third Angle Projection
Answer / naveen. First angle projection 1. The object is kept in the first quadrant. 2. The object lies between the observer and the plane of projection.
In first angle projection, that object is assumed to be in the first quadrant. Hence, the top view is projected below, i.e. to the x-z plane – which lies below the object. Hence when all the three view are drawn, you will get the top view below the front view.
