You are given a dimensioned isometric block in Figure 1. Orthographic views of this block are shown in Figure 2 to help you visualize the isometric drawing. Complete the following tasks for Question 1:

1.1 Redraw the isometric block in Figure 1 to a scale of 2:1. Use the orthographic views to help you visualize the block.

1.2 The orthographic views are labeled A, B, and C in Figure 2. Provide the description of each view. Indicate which orthographic view is shown and specify if it is in third angle or first angle projection.

Note: You do not need to redraw the orthographic views for Question 1.

Marks will be allocated as follows for Question 1:
- 1.1 Line work/Neatness of the isometric drawing [12 marks]
- 1.2 Layout of the isometric drawing, lightly show the isometric axis and any construction lines [4 marks]
- 1.3 Give the title block [2 marks]
- 1.4 Correct description of orthographic views given for Figure 2 [2 marks]

Answer :

Final answer:

The orthographic views in Figure 2 are labeled A, B, and C. View A is the front view, View B is the top view, and View C is the side view. These orthographic views represent a first-angle projection.

Explanation:

The orthographic views in Figure 2 are labeled A, B, and C. The description of each view is as follows:

  1. View A is the front view, which shows the object as it would appear when it is approached from the front.
  2. View B is the top view, which shows the object as if it was looked down upon from above.
  3. View C is the side view, also known as the end view, showing one of the sides of the object.

These orthographic views represent a first-angle projection, as indicated by the labeling of the views as per the first-angle projection convention.
