Fig. 5 shows the outline plan and sectional elevation S-S of part of a reservoir. The walls ABCD and EFGH of the reservoir are in the form of hyperbolic paraboloids.
(a) Using six elements in each direction on the surfaces ABCD and EFGH, complete the given plan and sectional elevation.
(b) Draw the vertical cross-section U-U through the reservoir.
(C) Determine the plane director for the edges AS and CD on the surface ABCD.
