What fits in Grand Ballroom
With a 6.1 m ceiling, a flown wall of Absen A2 Pro (2.97 mm) runs 72 tiles wide by 8 high (576 tiles, 36 x 4 m, 12096 x 1344 px) once you keep 1.5 m of trim under the bottom edge. That wall weighs about 5,760 kg and draws up to 106.6 kW (512 A at 208 V). Floor space after a 12 x 7 m stage seats roughly 3,778 theater, 1,545 banquet, or 1,062 classroom. The previz lets you move the wall, change the tile, and check sightlines from the back row.

Wall sizing assumes 1.5 m trim to the bottom edge, 0.3 m clearance under the ceiling, and a wall no wider than 80% of the longest wall. Weight and power are tile totals from the panel spec sheet; add processing, rigging, and cable.
