PERSPECTIVE VIEWS OF OBJECTS

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
Perspectives
are
classified by inclined
or
perpendicular
passing rays from
corners of objects to
the projection plane.
ISOMETRIC PERSPECTIVE
 Isometric perspective: Type of perspective which has same shortening ratio and
angles of perspective axis all over edges.
 Treatment procession during isometric perspective drawings:

DIMETRIC PERSPECTIVE
 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.

SLOPED PERSPECTIVE:
 Sloped perspective: Type of perspective which has inclined looking sight
according to projection plane and paralled drawed edges.
 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.
