Question 1

The foreshortening factor is the ratio of
A)actaul lengh of line to its projected length
B)projected length of line to its true length
C)both of these
D)none of these

Accepted Answer

The foreshortening factor is defined as the ratio of the projected length of a line to its true length.

Question 2

In perspective projection , the lines of projection conerges at single point called
A)center of projection
B)projection reference point
C)both of these
D)none of these

Accepted Answer

In perspective projection, the lines of projection converge at a single point known as both the center of projection and the projection reference point.

Question 3

_________ projection produces relalstic view but does not preserve relative proportions
A)serial
B)parallel
C)perspective
D)any

Accepted Answer

Perspective projection produces realistic views by mimicking how the human eye sees. It creates a sense of depth and dimension but does not preserve the relative proportions of objects, as objects further away appear smaller.

Question 4

cabinate projection appear _______ realistic compare to cavilier projection
A)more
B)less
C)equally
D)none of these

Accepted Answer

Cabinet projection appears more realistic compared to cavalier projection because it uses a scale factor of 1/2 for the receding lines, reducing distortion and making objects appear more proportionate.

Question 5

The oblique projection are classified as _____ and ______ projections
A)cavikier and cabinate
B)serial and parallel
C)parallel and perspective
D)isometric and dimetric

Accepted Answer

Oblique projections are classified into cavalier and cabinet projections, which are methods of drawing objects in three dimensions.
