Worked Solution & Example Answer:The 3D graphic on the right shows a model of a structure from a crazy-golf park - Leaving Cert DCG - Question B-3 - 2021
Step 1
Draw the given elevation and incomplete plan of the structure.
Answer
-
Given Elevation: Begin by sketching the provided elevation based on the dimensions. Ensure to accurately incorporate the highest points, the width of the tunnel, and the length of the structure that connects to the tunnel.
-
Incomplete Plan: Over a suitable scale, draw the incomplete plan by starting with the outer outline. Clearly indicate the location of the tunnel, its orientation, and any other features visible from above.
-
Details: Ensure that both drawings maintain a 1:1 scale for consistency, and label each part appropriately.
Step 2
Complete the plan, showing all lines of interpenetration between the tunnel and both ends of the structure.
Answer
-
Interpenetration Lines: Analyze the points at which the tunnel intersects with the structure's sides. Draw dashed lines across the plan to indicate these lines of interpenetration.
-
Reference Points: Use reference points from the elevation to correctly transfer widths and heights from the elevation to the plan. This step is crucial to maintaining accuracy.
-
Final Checks: Double-check that all dimensions correspond correctly with those presented in the elevation and adjust as necessary to ensure that the plan remains true to the 3D interpretation.
Step 3
Draw an end view of the structure.
Answer
-
Transfer Widths from Plan: Reference the previously drawn plan to accurately transfer the widths onto the end view, ensuring proportions are maintained as per the scale.
-
Projection of Heights from Elevation: From the elevation drawing, project the heights onto the end view to provide depth to the structure.
-
Details in End View: Incorporate all hidden details such as the tunnel's elevation within the end view. Use dashed lines to represent parts not visible from this angle.
-
Final End View: Ensure that the end view is properly constructed with clear labels identifying each component, along with hidden lines to demonstrate the structure's complete form.
