Worked Solution & Example Answer:The image on the right shows a modern chair design - Leaving Cert DCG - Question A-4 - 2022
Step 1
Complete the elevation.
Answer
To complete the elevation, you need to follow the guide lines and structure provided in the image. Begin by identifying the curvature of the plywood back based on the existing lines. Using a compass, draw the required arcs to complete the shape of the design, ensuring that the curvature matches the intended design. Incorporate the horizontal and vertical lines to align with the existing elevation and maintain proportions.
Step 2
Complete the surface development.
Answer
For the surface development, begin by tracing the outline of the truncated cylinder. You will need to project the points defined in the elevation onto the surface view. Use the grid layout provided in the marking scheme to accurately position the points and create a flat representation of the curved surface. Ensure that the dimensions match the required specifications, and connect the points using straight lines to outline the developmental shape.
