Worked Solution & Example Answer:The 3D graphic on the right shows a child's playhouse which is made from plastic - Leaving Cert DCG - Question B-2 - 2009
Step 1
Draw the given plan
Answer
-
Understand the drawing: Begin by analyzing the provided plan and elevation.
-
Draft the layout: Use the specified scale of 1:20 to accurately represent the dimensions:
- Length: 1200mm
- Width: 600mm
- Height: 800mm
- Other features as per the elevation.
-
Create the drawing: Draw the playhouse plan, ensuring all elements are to scale and correctly positioned based on the elevation reference.
Step 2
Make a perspective drawing of the structure
Answer
-
Identify the points:
- Spectator point (S) is 1440mm from corner A.
- The picture plane (PP) is tangent to corner A.
- The ground line (GL) is horizontal and at 1000mm vertical height.
-
Locate the points in relation to the drawing:
- Mark the position of corner A on the drawing.
- Measure and plot the spectator point (S) 1440mm from corner A along the ground line.
- Draw the picture plane (PP), ensuring it touches corner A and orienting it correctly.
-
Construct vanishing points:
- From the spectator point (S), draw lines converging to the vanishing point (VP). Use these lines to define the edges of the structures going back to the horizon line.
-
Draw the perspective:
- Using the above measurements and lines, construct the perspective view of the structure, ensuring it reflects the correct proportions and angles.
