PERSPECTIVE VIEWS OF OBJECTS

The drawings are called as perspective that is explanation of 3 dimensional(volumetrical) views of objects by choosen 3 surface.

Perspective drawings provide to explanation the visible outside edge andplanes of objects.

Perspective Drawing Methods:

1. Method of parallel perspective: Generally it’s used for drawings of machine parts and so on small sized parts. Also puts account for structure drawings too.

2. Method of coned (Inclined) perspective: Generally it’s used by architectures.

Perspectives areclassified by inclinedor perpendicularpassing rays fromcorners of objects tothe projection plane.

PERSPECTIVE VIEWS OF OBJECTS

Isometric perspective: Type of perspective which has same shortening ratio and angles of perspective axis all over edges.

Dimetric perspective: Type of perspective which has same length and angle displaying 2 of 3 main dimension edges, other one has 1:2 scale and different angle.

DIMETRIC PERSPECTIVE

Sloped perspective: Type of perspective which has inclined looking sightaccording to projection plane and paralled drawed edges.

SLOPED PERSPECTIVE:

Type of sloped perspectives:

1. Cavalier (oblique) perspective: Back axis angle is 30o, 45o or 60o and depth measurement has a 1:1 scale.

SLOPED PERSPECTIVE:

2. Cabinet perspective: Back axis angle is 45o and depth measurement has a 1:2, 3:4 scales.
