In the plan view, to illustrate the elements and their divisions:

1. Show a grid of lines dividing the surface into equal sections. This represents the elements of the surface.
2. Ensure that the division matches the height of 55 units and mark additional lines at 30° and 60° inclined angles corresponding to the curvature.

For the elevation:

1. Begin with the vertical projection of ABCD.
2. Highlight the curved outline as described in the image above.
3. Indicate the heights, ensuring that the outward curvature resembles the hyperbolic section shown.

In the elevation view:

1. Sketch the vertical divisions using lines that curve outward, reflecting the surface shape.
2. Maintain consistency in spacing within the element divisions from A to C.

Finally, for the curve in elevation:

1. Draw the hyperbolic curve accurately using smooth lines.
2. Indicate the part of the surface between points B and D with arrows to show flow and direction, capturing the essence of the hyperbolic shape.

To determine the heights and widths:

1. Identify the maximum height from point D or B, which is 60 units.
2. The width, based on the end sections of ABCD, is indicated to be 55 units.

Outline the hyperbolic paraboloid by:

1. Creating a smooth curve connecting all identified points that depict the surface profile.
2. Ensure the proportions reflect the actual dimensions derived from both plan and elevation.

Draw the elements of the surface:

1. Mark horizontal lines through the newly established outline, parallel to the base rectangle.
2. Add vertical lines that align with the previously drawn elevations and connect the points in three-dimensional form.

To depict the curve in the end view:

1. Show a gentle curve rising above the base A to B, indicating the hyperbolic section.
2. Ensure the curvature looks realistic, matching the height perspectives from previous drawings.
