Step 1
Draw the given elevation of the structure.
Answer
To draw the elevation of the structure, begin by outlining the rectangular shape of the parabolic surface. Represent the point B as the vertex, from which the parabola ABC is defined. Ensure that the curve is drawn on both the right-hand side (RHS) and the left-hand side (LHS) to depict symmetry. The drawing should indicate the height and depth accurately, showing the arc's elevation.
Step 2
Draw the end view of the generating parabola ABC.
Answer
For the end view, sketch a rectangular outline of the parabolic cross-section as seen from the end. Focus on determining points along the parabola ABC, marking significant points such as A, B, and C. Use construction lines to accurately reflect the curvature of the parabolic shape. The view should appear symmetrical as well.
Step 3
Project the plan of the structure.
Answer
In the plan view, locate the key points A, C, E, and D. Establish the widths along the RHS and LHS in the plan. Draw the parabola's curve in the plan, ensuring that the points reflect the same dimensions as in elevation and end view. The plan should capture the essence of the three-dimensional shape into a two-dimensional representation.
Step 4
Determine the true shape of surface AEC.
Answer
To find the true shape of surface AEC, establish the widths through auxiliary views. Locate critical points on the curve AEC to help visualize its structure accurately. Finally, draw the true shape curve based on the previously identified points, illustrating the contour of the surface and ensuring that the flow of the curve is smooth and continuous.
