Why can not use second angle and four angle projection method in Engineering drawing?
Because in second angle both quaderent comes negative that's why we cant use second angle method
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 advantage does first angle orthographic projection have over third angle orthographic projection?

Where has third angle projection been used?
thrid angle projection is officially used in Australia, for a fact, not lying!!
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.
What are the two main types of projection in autocad?
first angle, third angle
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
What is isometric projection in AutoCAD?
It is 3D view at an angle and diminishing into the distance.
What is the definition of angle of projection?
the angkle of projection is an angle and the projection
Why can not use second angle and four angle projection method in Engineering drawing?
Because in second angle both quaderent comes negative that's why we cant use second angle method
Why drawings are not drawn in second and fourth angle projection?
because in 2nd and 4th angle,both the view is going to overlap with each other,so we cant able to visualise the drawing properly,so we are not drawing in 2nd and 4th angle. kash answer kash_115@yahoo.com
What are the 2 types of oblique drawing?
first angle projection and third angle projection.
What direction do you face in orthographic projections?
its always in front of d vertical plane..however there are 4 methods of projection 1st angle second angle 3rd angle and fourth angle..but 1st and 3rd are preffered as the views come distinct in second and forth the views are placed one over the other causing trouble in identifying d views
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
Why second and third angle projections not used in orthographic projections?
because 2nd and 4th angle projection overlap each other
Why do you not use second angle projection and fourth angle projection?
Method of Projections tell us the positions of the views where they are projecting on the Planes. Consider 1st Angle of projection, All the views from a particular direction are projected on the opposite side, while in 3rd Angle of projection, All the views from a particular direction are projected on the same side. Take a case of 2nd Angle of Projections( means object lies in 2nd Quadrant) since the image is to be formed on the planes only that is why we have to keep right side view on the same side from viewing while top view on the opposite side from viewing. This contradicts view placement( i.e. once you are placing on same side and once on Opposite). Same is applicable in 4th Angle of Projection also.
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.
