Any space can be divided into 4 quadrants basically using two mutually perpendicular planes - the horizontal plane(HP) and the vertical plane(VP). These planes are considered to be transparent and to be of infinite size.
In first angle projections, the object is considered to be in front of VP and above HP. Hence the top view or plan of the object will be obtained below the reference line and the front view or elevation above the reference line.
In third angle projections, the object is said to be behind VP and below HP. hence the top view or plan will be obtained above the reference line and the elevation below the reference line.
What else can I help you with?
Can you show me the difference between first and third angle projection?
In a first angle projection, the object stands in between the observer and the plane of projection. In a third angle project, the object and the plane of projection is interchanged.
What is the difference between first and third angle protection?
First angle projection and third angle projection are two methods of orthographic projection used in technical drawings. In first angle projection, the object is placed in the first quadrant, meaning the view is projected onto the plane behind the object, resulting in the top view appearing below the front view. In contrast, third angle projection places the object in the third quadrant, with the views projected onto the planes in front of the object, making the top view appear above the front view. These conventions are used to standardize how drawings are interpreted, with first angle commonly used in Europe and third angle in the United States.

What are first angle and third angle project?
First angle and third angle projection are two methods of creating orthographic projections of 3D objects in technical drawing. In first angle projection, the object is positioned between the observer and the projection plane, resulting in the top view appearing below the front view and the right side view appearing to the left. Conversely, in third angle projection, the object is placed behind the projection plane, which positions the top view above the front view and the right side view to the right. These projection methods are standardized in different regions, with first angle commonly used in Europe and third angle prevalent in the United States.
What is different between 1st angle and 3rd angle?
Basically its just where you position the views of the main object, in first angle projection, if you view the object from the left, the view is drawn to the right of the object, in third angle projection, its drawn on the viewing side.
Can you show me the difference between first and third angle projection?
In a first angle projection, the object stands in between the observer and the plane of projection. In a third angle project, the object and the plane of projection is interchanged.
What is difference between 1st angle and 3rd angle projection?
Both third angle and first angle projection display the standard three orthographic views of a part or assembly on a drawing.. The key difference between third angle and first angle is the layout of the part on the sheet.
What are the 2 types of oblique drawing?
first angle projection and third angle projection.
What is the difference between first and third angle protection?

Which countries are using second angle of projection?
any country using in second r fourth angle projection r else what r the advantages between first angle and third angle projetion
Distinguish between First Angle Projection method and third angle projection method?
right side view draw in left side and left side view draw in right side is called third angle projection
What are the advantages of third angle projection over the first angle projection?
Neglecting term "opposite".. In third angle projection, what we see are what are we going to draw

What are the two main types of projection in autocad?
first angle, third angle
Symbol for first angle projection?
A cone shown in a circle
