Question 1
Draw the plan elevation of the following shape:
Select the correct answer from the list below:
A:
B:
C:
D:
CORRECT ANSWER: B
WORKED SOLUTION:
The plan elevation is looking down on the shape from directly above, so will be a square.
However, we have to take the sides of the triangles into consideration as well, which will form a cross.
So, the plan elevation will be
Question 2
Given the following shape, draw the side elevation.
Select the correct answer from the list below:
A:
B:
C:
D:
CORRECT ANSWER: D
WORKED SOLUTION:
Looking at the shape we can see that it is one block high and three blocks wide, so the side elevation will be.
Question 3
Construct a drawing of the 3D shape described by the plan and elevations.
Select the correct answer from the list below:
A:
B:
C:
D:
CORRECT ANSWER: A
WORKED SOLUTION:
From the plan view we can see that the shape will be 3 cubes in a single row, but we don’t know anything about the height yet, so all we can say is that it will look like a big wall that is 1 deep and 3 wide:
The side elevation gives us the information about the height, showing that it will be 2 high.
And finally, the front view shows us that the top middle cube is missing.
Question 4
Construct a drawing of the 3D shape described by the plan and elevations.
Select the correct answer from the list below:
A:
B:
C:
D:
CORRECT ANSWER: C:
WORKED SOLUTION:
From the plan view, we can see that the shape will be 3×3 with a cube missing in the middle. We don’t know anything about the height, so we know it will look something like this:
The front elevation gives us more information, telling us that the shape will be two cubes tall and the top middle row will be missing.
Finally, the side elevation tells us that we will only have the back row, so we can remove the front two.
Question 5
Construct a drawing of the 3D shape described by the plan and elevations.
Select the correct answer from the list below:
A:
B:
C:
D:
CORRECT ANSWER: A
WORKED SOLUTION:
From the plan view, we can see that the shape will look a bit like an L, or that it is 3×4 with a 2×2 chunk missing in the top right corner. We don’t know anything about the height, so we know it will look something like this:
The front elevation gives us more information, telling us that:
a) The shape will be three cubes high.
b) Only the first two cube on the top row will be blue.
c) The third and fourth cube on the top row shouldn’t be there, and there shouldn’t be any going through the middle on the bottom rows.
Finally, the side elevation tells us that a) the bottom should only consist of the two cubes that look a little bit like legs (removing that cube that only shows as a green triangle between them).
b) The top back row shouldn’t be there.
c) The green cube in the middle should be yellow.
