Worked Solution & Example Answer:The 3D graphic on the right shows a model of a tent which has a side window - Leaving Cert DCG - Question B-3 - 2010
Step 1
Draw the given plan
Answer
To complete this step, refer to Fig. B-3. Begin by accurately drawing the outlined structure of the tent based on the provided plan and elevation views. Use a 1:1 scale as indicated. Ensure all measurements are precise:
- Width of the structure: 90mm
- Length of the structure: 60mm
- The height at the peak should match the elevation.
- Remember to include the side window as per the elevation diagram.
Step 2
Make a perspective drawing of the structure
Answer
To create the perspective drawing, follow these guidelines:
-
Plan of spectator, PP, VP1, and VP2: Draw the plan showing the position of the spectator point (S) 70mm from corner A. Mark the vertical and horizontal vanishing points (VP1, VP2) to guide your perspective.
-
Elevation of GL, HL, VP1, and VP2: On the elevation, indicate the ground line (GL) and the horizon line (HL), maintaining the perspective view to get accurate heights.
-
Sight lines from spectator to plan: Draw the sight lines from point S to the edges and important features of the tent structure; this helps visualize depth.
-
Perspective of bottom edges: Use the vanishing points to draw the bottom edges of the structure accurately, ensuring they recede towards the vanishing points.
-
Establish heights: Determine and establish the heights for main components, making sure all parts conform to the perspective rules.
-
Completion of main structure: Add details and complete the tent structure based on the established heights and perspective lines.
-
Establish height for top of window opening: Measure the location of the top edge of the window based on the side view provided in Fig. B-3.
-
Establish height for bottom of window opening: Similarly, establish the height of the bottom edge of the window.
-
Completion of window: Draw the window, ensuring it aligns with the previously established heights.
-
Completion of inside of tent: Add details of the tent’s interior as necessary.
-
Presentation: Ensure the overall drawing is neat and presentable, with clearly marked dimensions and lines.
