Worked Solution & Example Answer:The image shows 'Cloud Gate', an iconic sculpture located in Chicago's Millennium Park - Leaving Cert DCG - Question B-1 - 2017
Step 1
Draw the given elevation, showing clearly the constructions for the ellipse and the parabola.
Answer
To draw the elevation:
- Start by drawing the major and minor axes of the ellipse, ensuring the dimensions are accurate: major axis length of 18m and minor axis length of 6m.
- With the correct center point, construct the ellipse using a compass or equivalent method to achieve smooth curves.
- Next, draw the parabolic curve DEF. Mark the vertex at point E as indicated and ensure the parabola is proportionally scaled relative to the ellipse.
- Indicate the removal of the parabolic section clearly in the elevation view.
Step 2
Draw the elliptical outline of the sculpture in the plan view.
Answer
In the plan view, draw the outer ellipse representing the top view of the sculpture. Begin by sketching the major axis horizontally and the minor axis vertically, ensuring the ellipse fits within the specified dimensions. The semi-minor axis will be projected down to 6m and the semi-major axis laterally extended to 18m. Ensure it meets the correct proportions.
Step 3
Draw the outline and view.
Answer
To illustrate the outline and view, use a bold line to solidify the outer edges of the sculpture's base, maintaining the curvature from the plan view. Ensure the width matches the 18m and height aligns vertically with the desired sculpture height, corresponding to the elevation views shared.
Step 4
Use appropriately spaced vertical sections to complete the plan and view.
Answer
For the vertical sections, use evenly spaced markers along the horizontal and parabolic cut in the elevation. For the parabolic cut, draw vertical lines to indicate points of intersection. Ensure the curved section at the base is accurately represented in both plan and elevation to provide clarity on the sculpture's dimensions.
