In this article, we will discuss 3rd angle projection.
In this projection, the object is kept in the third quadrant. The object is kept behind the vertical planes and the bottom of the horizontal plane. Third angle projection is commonly utilized in the United States and Australia. The projection planes lie between the object and the observer. The plane of projection is considered transparent in 3rd angle projection.
