## What is the difference between first and third angle drawings?

In third-angle projection, the view of a component is drawn next to where the view was taken. In first-angle projection, the view is drawn on the other end of the component, at the opposite end from where the view was taken.

## What are third angle drawings?

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 are first angle drawings?**

First-angle projection: In this type of projection, the object is imagined to be in the first quadrant. Because the observer normally looks from the right side of the quadrant to obtain the front view, the objects will come in between the observer and the plane of projection.

**What is the symbol of Third angle Projection?**

The third angle symbol is shown in Figure 1. It is represented by the circular top view of the cone with the right view of the cone to the right of it. In the right-side view, the narrow end of the cone is pointed towards the top view.

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.

**Which is better 1st or 3rd angle projection?**

In the first angle projection, the object is placed in the 1st quadrant….Difference between First Angle Projection and Third Angle Projection :

SR.NO | First Angle Projection | Third Angle Projection |
---|---|---|

5 | Top view at the bottom of the horizontal axis. | Top view at the top of horizontal axis. |

6 | Right view is at the left side of vertical axis. | Right view is at the right side of vertical axis. |

## What is 1st & 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.

## What is the difference between first and third angle projection?

To get first angle projection object is place in between the plane of projection and observer and for the third angle projection plane of projection is placed between the object and observer. State of Projection Plane. In first angle of projection plane of projection is taken solid while in third angle of projection it is taken as transparent.

**What is first and third angle projection?**

Both first angle and third angle projection are the two ways of drawing in orthographic that usually consists of three different views of an object in two dimensions. They are used to obtain engineering drawings for clarity.

**What is the symbol for third angle projection?**

The symbol of first and third angle projections itself explains their significance. Symbol of first and third angle method of projection indicates a frustum of cone which is led horizontally on the surface.
