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 and planes 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.

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.
Treatment procession during isometric perspective drawings:
ISOMETRIC PERSPECTIVE

ISOMETRIC PERSPECTIVE
Treatment procession during isometric perspective drawings of inclined surfaces:
ISOMETRIC PERSPECTIVE
Treatment procession during isometric perspective drawings of sloping surfaces:
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
Axial angles and edge lengths of dimetric perspective:
DIMETRIC PERSPECTIVE
Treatment procession during dimetric perspective drawings:
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.
