Worked Solution & Example Answer:The 3D graphic on the right shows the outline of a house and conservatory - Leaving Cert DCG - Question B-3 - 2014
Step 1
Draw an elevation of the structure in the direction of the arrow.
Answer
To draw the elevation, observe the isometric view carefully. Start by sketching the rectangular outline of both the house and the conservatory. The height of the house is 15 units, and the conservatory is 15 units tall. Make sure to indicate the roof's slope and the doorway of the conservatory clearly in your elevation.
Step 2
Project a plan from the elevation.
Answer
Begin by drawing the outline of the house in plan view, using the dimensions provided. The length of the house is 60 units, and the width is 30 units. Ensure that the width includes the conservatory, which has an additional 15 units. Clearly define the outline of the conservatory within this plan, and mark the entrance accordingly.
Step 3
Draw an auxiliary elevation of the structure, projected from the plan.
Answer
To complete the auxiliary elevation, first draw the line X1Y1, parallel to the plan of surface A. Next, project the height details from the plan to the auxiliary elevation. Make sure to accurately transfer the height measurements for surface A from the elevation. Clearly indicate surface A in the auxiliary elevation, paying close attention to its apparent shape and size, and make sure all lines are neatly presented.
