 1.  
For the given foundation plan, select the orthographic drawing set.


a.
Set 2
b.
Set 4
c.
Set 3
d.
Set 1


Solution:

An orthographic drawing shows the top view, front view and right-side view of a three-dimensional figure.


The following three-dimensional figure can be developed from the given foundation plan.


The top view, front view and right-side view of the given object are as shown.

Set 3 represent the orthographic views of the three-dimensional figure.


Correct answer : (3)
 2.  
Find the number of cubes required to make the structure.


a.
15
b.
16
c.
17
d.
14


Solution:

Count the number of cubes in the structure.

The number of cubes required to make the structure are 16.


Correct answer : (2)
 3.  
Select the incorrect statement.
a.
An isometric drawing shows the corner view.
b.
An isometric drawing is used to represent two dimensional drawing only.
c.
An orthographic drawing shows a top view, front view and right-side view.
d.
A foundation diagram shows the base of a structure and the height of each part.


Solution:

An isometric drawing is a type of three-dimensional drawing.

It shows three sides of an object in a single drawing.

An isometric drawing of a three-dimensional object shows a corner view of the figure.

So the statement, 'An isometric drawing is used to represent two-dimensional drawing only' is the incorrect statement.


Correct answer : (2)
 4.  
What type of view does the following figure represent?


a.
Isometric view
b.
Right-side view
c.
Top view
d.
Front view


Solution:

The given figure is three-dimensional.

An isometric drawing is a pictorial diagram that shows three faces of an object in one view.

An isometric drawing shows a corner view. So, it is an isometric view.


Correct answer : (1)
 5.  
For the given foundation plan, select the isometric drawing.


a.
Figure 2
b.
Figure 1
c.
Figure 4
d.
Figure 3


Solution:

An isometric drawing is a pictorial diagram that shows three faces of an object in one view.


The following three-dimensional figure can be developed from the given foundation plan.

Figure 3 represents the isometric drawing for the given foundation plan.


Correct answer : (4)
 6.  
Select the foundation diagram for the isometric drawing.

a.
Figure 2
b.
Figure 3
c.
Figure 4
d.
Figure 1


Solution:

An isometric drawing shows a corner view of a three-dimensional figure.

A foundation drawing shows the base of the structure and the height of each part.


Count the number of blocks the isometric drawing has in each row on its base.

Figure 1 gives the foundation drawing of the three-dimensional figure.


Correct answer : (4)
 7.  
Recognize the foundation plan for the given stucture.


a.
Figure 3
b.
Figure 4
c.
Figure 2
d.
Figure 1


Solution:

The given structure is a three-dimensional figure.

A foundation drawing shows the base of the structure and the height of each part.


Count the number of blocks the isometric drawing has in each row on its base.

Figure 3 gives the foundation drawing of the three-dimensional figure.


Correct answer : (1)
 8.  
What type of view does the cake represent?

a.
Left-side view
b.
Top view
c.
Front view
d.
Right-side view


Solution:

An orthographic drawing shows a top view, front view and right side view.

Only the top of the cake has been shown in the picture.

So, it is a top view.


Correct answer : (2)
 9.  
Identify the structure that is constructed using 5 cubes.


a.
Figure 1
b.
Figure 3
c.
Figure 2
d.
Figure 4


Solution:

Count the number of cubes in each structure.

Figure 2 is a structure constructed using 5 cubes.

Figure 3 is a structure constructed using 9 cubes.

Figure 1 is a structure constructed using 6 cubes.

Figure 4 is a structure constructed using 8 cubes.

Hence Figure 2 is the answer.


Correct answer : (3)
 10.  
Recognize the view for the given isometric figure.


a.
Front view
b.
Right side view
c.
Left side view
d.
Top view


Solution:

The given figure is three-dimensional.

An orthographic drawing shows a top view, front view and right-side view.

The view that is shown in the figure is the front view.
