Question 16
This is the plan view of a 3D object. Complete the diagram below to show the front view of the 3D object from A.
Worked Solution & Example Answer:This is the plan view of a 3D object - OCR - GCSE Maths - Question 16 - 2019 - Paper 1
Step 1
Second column any height but wider than, and right of, first with roughly middle vertical and flat top
Answer
In the front view, I will represent the first object as a square block, which will be shown as a rectangle in the front view. The second shape depicted as a diamond will appear as a taller rectangular column beside the square block.
This means that the first object will maintain its width in representation, while the second will be slightly wider but not exceeding the limits of a well-proportioned rectangular prism in front view.
Thus, from point A, the front view will illustrate both the square base and the rectangular column.
Step 2
For roughly rectangular column within ± 2 mm (between inner and outer overlay circles) and no oblique top
Answer
The rectangular column will have vertical lines drawn around it to emphasize its dimensions, maintaining the correct aspect ratio with the overall design to avoid any oblique shapes. These lines should be straight and parallel, representing the height without tilting.
Furthermore, the base of the rectangular column must be shown as being aligned with the base of the square block to clearly demonstrate their spatial relationship from the front perspective.
Step 3
For approx vertical line approx central
Answer
A vertical line will be drawn centrally on the rectangular column in the front view. This line not only emphasizes the column's depth but also assists in visually balancing out the 3D object when viewed from A. The accuracy of this line is important to ensure a well-proportioned and representational sketch.
