Why we need two angle of projections ( 1st angle and 3rd angle)? Cant we standardize to one...

Answer / kaushal meena

Generally 1st angle projection is used in India and 3rd
angle projection is used in European countries. These two
view are used because these two views provides enough planes
to draw the geometric view of body, in 2nd angle and 4th
angle we dont get these planes so we use 1st angle and 3rd angle

Why we need two angle of projections ( 1st angle and 3rd angle)? Cant we standardize to one...

Answer / subbu

Generally 1st angle projection is used in India and 3rd
angle projection is used in European countries. In 1st and 3rd angle projections there is no overlapping of principal planes while drawing side and top views. but in 2nd and 4th angle projections the principal planes are overlapped while drawing top and side views. It results confusion in drawing. For this reason 1st and 3rd angle projections are used commonly.
