Question 1

The foreshortening factor is the ratio of&#10;A)actaul lengh of line to its projected length&#10;B)projected length of line to its true length&#10;C)both of these&#10;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&#10;A)center of projection&#10;B)projection reference point&#10;C)both of these&#10;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&#10;A)serial&#10;B)parallel&#10;C)perspective&#10;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&#10;A)more&#10;B)less&#10;C)equally&#10;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&#10;A)cavikier and cabinate&#10;B)serial and parallel&#10;C)parallel and perspective&#10;D)isometric and dimetric

Accepted Answer

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