Worked Solution & Example Answer:The drawing on the right shows the plan and the partially completed perspective drawing of the end portion of a GAA pitch - Leaving Cert DCG - Question A-4 - 2019
Step 1
Complete the perspective drawing of the given end portion of the pitch.
Answer
To complete the perspective drawing:
- Begin with the given lines representing the left-hand side of the pitch. Use the left vanishing point (VP1) to project the lines into perspective.
- For the 20m and 13m lines, draw lines extending from their endpoints horizontally towards the vanishing points. This establishes the correct angles for the sides of the pitch.
- Next, for the large rectangle representing the pitch area, outline the corners and connect them back to their respective vanishing points to create the depth.
- Finally, draw the small square/rectangle for the goalposts, ensuring to connect them back to the vanishing points appropriately.
Step 2
Determine and show the true height of the goalpost upright.
Answer
To determine the true height of the goalpost upright:
- Measure the distance from the top of the goalpost to the existing perspective line (PP) and the ground line (GL).
- Using the proportions established in the perspective drawing, apply the same dimensions to represent the upright in true height.
- Finally, illustrate the vertical measurement directly on the drawing to show the true height visually, indicating that the goalpost is upright.
