Worked Solution & Example Answer:The 3D graphic shows an entrance to a house - Leaving Cert DCG - Question B-1 - 2009
Step 1
Draw the given plan and elevation
Answer
To complete this part of the question, begin by drafting the plan view of the entrance, ensuring that the dimensions are accurately represented as specified:
- The pier height is 600mm and extends 400mm wide.
- The wall should align with the specified measurements: 940mm in length and all heights and angles correctly depicted. Additionally, ensure that the gate design is clear. This elevation provides a simple, yet detailed view of the entrance as shown in Fig. B-1.
Step 2
Draw an auxiliary elevation of the pier and wall, projected from the plan
Answer
For this part, start by establishing the auxiliary view from the plan. This involves projecting lines from the plan to the right side elevation. Here are the necessary steps:
- Identify point A on the plan and project it vertically according to the height measurements.
- Create the true size of the surface A by using its angles from the given dimensions, ensuring the 60-degree angle is accurately represented along with its dimensions of 400mm.
- As a final touch, ensure that the necessary dimension lines are clear and legible to present a complete, accurate auxiliary elevation.
