Introduction to Projection methods

A typical multiview drawing includes what views? (Select All that Apply)

• Top View

• Front View

• Right Side View

• Back View

Which of the following describes the theory of orthographic projection?

• projectors are parallel to each other and perpendicular to plane of projection.

• projectors are parallel to each other and parallel to plane of projection.

• projectors are perpendicular to each other and perpendicular to plane of projection.

• projectors are perpendicular to each other and parallel to plane of projection.

Orthographic projection represents three dimensional objects in

• One dimension

• Two dimension

• Three dimension

• All of the above

XY line is also known as

• horizontal line

• vertical line

• reference line

• all of these

In first angle projection, the relative position of object is ______________ plane and observer.

• object is placed in between

• plane is placed in between

• observer is placed in between

• any of these

In orthographic projection, observer is assumed to be at

• infinity

• in front of object

• behind of object

• anywhere

If an object lies in third quadrant, its position with respect to reference planes will be

• infront of V.P, above H.P

• behind V.P., above H.P.

• behind V.P., below H.P.

• infront of V.P., below H.P

If an point lies in first quadrant, its position with respect to reference planes will be

• in front of V.P, above H.P

• behind V.P., above H.P.

• behind V.P., below H.P

• in front of V.P., below H.P

In orthographic projection, the top view represents:

• The object as seen from above

• The object as seen from the side

• The object as seen from below

• The 3D appearance of the object

Which type of sketch is the MOST realistic in appearance but the most complex to draw?

• isometric

• oblique

• orthoscopic

• perspective
