What is 3rd angle of 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.
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 projection differentiate between the First and Third angle projection?
The object is placed between the observer and projection planes. The plane of projection is taken solid in 1st angle projection….Difference between First Angle Projection and Third Angle Projection :
| SR.NO | First Angle Projection | Third Angle Projection |
|---|---|---|
| 7 | Left view is at the right side of vertical axis. | Left view is at the left side of vertical axis. |
What is the difference between 1st angle and 3rd angle projection with neat sketch?
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….Difference between First Angle Projection and Third Angle Projection :
| SR.NO | First Angle Projection | Third Angle Projection |
|---|---|---|
| 3 | The plane of projection is opaque. | The plane of projection is transparent. |
