Drag any corner. It moves the measurement behind
it, so the pool stays a hopper whatever you pull.
The three hopper sides are on different angles. Turn on
Match the three hopper sides in the editor to bring them together.

Why the bottom is shaped like that
This is a hopper bottom — the standard vinyl-liner build.
The deep floor is not the full width of the pool: it is a rectangle sitting
in the middle, with angled skirts (the coves) rising from all of
its edges up to a common line
2.5 ft below the surface. That line is
halfway down the deep end wall, which is why the deep wall only looks
vertical for its top half.
The ramp at the deep end runs 4 ft
horizontally while rising 2.5 ft, so it climbs at roughly
45°. The side coves use that same angle, which is what fixes the deep floor
at 12 × 15 ft.
One consequence worth seeing in the model: the coves taper to nothing at
both ends on their own — at the deep wall, where the ramp has already
lifted the floor back to the cove line, and partway up the transition
slope, where the floor rises above it. Nothing in the geometry special-cases
that. It falls out of the rule that the walls stay vertical until the floor
drops past the halfway mark.
