Worked Solution & Example Answer:The image below shows a set of inflatable geometric shapes for a children's outdoor play area - Leaving Cert DCG - Question A-3 - 2022
Step 1
Draw the plan of the sphere C.
Answer
-
Construct the plan of the sphere C:
Start by drawing a circle that represents the plan view of the sphere C, ensuring it is placed in the correct orientation relative to the other shapes in the drawing. The circle should reflect the diameter as seen in the elevation.
-
Projection drawing:
From the elevation of sphere C, project vertical lines down to the plan view. This will help ensure the plan is accurately represented based on the elevation.
-
Locating the center point:
Mark the center of the circle in the plan view. It should correspond to the center point in the elevation view. Use construction lines to ensure accuracy.
-
Finalizing the drawing:
Review the plan and circle to ensure all elements are connected correctly without any disconnections. Add any necessary annotations for clarity.
Step 2
Complete the plan, showing all hidden detail.
Answer
-
Complete cone A:
Continue by drawing the plan of cone A, ensuring it is accurately placed and drawn to reflect its hidden and visible parts. Use dashed lines to indicate hidden edges of the cone.
-
Add hidden detail:
For cylinder B, include any hidden details as needed, using appropriate line types (e.g., dashed lines) to indicate parts not visible in the current perspective.
-
Presentation:
Ensure the overall drawing is neat and follows the required presentation rules. Include labels and dimensions where necessary for clarity.
