Worked Solution & Example Answer:The image on the right shows a case for holding reading glasses - Leaving Cert DCG - Question B-1 - 2020
Step 1
Draw the given end view, plan, and elevation.
Answer
- End View: Start by sketching the end view of the triangular case at a scale of 1:1. The outline should reflect the triangular prism shape with correct dimensions.
- Plan View: Next, create the plan view showing the top face of the case. Ensure that the sides are accurately represented and include any openings or features that are visible from the top.
- Elevation View: Finally, draw the elevation view. This should show both the height and width of the triangular prism and be correctly proportioned according to the dimensions given.
Step 2
Draw the plan and elevation of the sticker rst.
Answer
- Plan of the Sticker rst: Based on the triangular shape specified, sketch the equilateral triangle in plan view. Its sides should be equal and appropriately aligned with surfaces A, B, and C of the case.
- Elevation of the Sticker rst: For the elevation, represent the triangle showing its height. Include any necessary notations that indicate the positioning of the sticker relative to the case.
Step 3
On a separate diagram, draw a one-piece surface development of the case.
Answer
- Surface Development: Begin by unfolding the surfaces A, B, and C. The development should show these surfaces laid flat.
- Include the Outline of the Sticker rst: Ensure that the position of the sticker rst is clearly marked on the surface development. This will help indicate where the sticker will be applied once the case is assembled.
