What fits in Center Hall (CH)
With a 7.9 m ceiling, a flown wall of Absen A2 Pro (2.97 mm) runs 99 tiles wide by 12 high (1188 tiles, 49.5 x 6 m, 16632 x 2016 px) once you keep 1.5 m of trim under the bottom edge. That wall weighs about 11,880 kg and draws up to 219.8 kW (1057 A at 208 V). Floor space after a 12 x 7 m stage seats roughly 4,029 theater, 1,648 banquet, or 1,133 classroom. The previz lets you move the wall, change the tile, and check sightlines from the back row.

Planning notes
No rigging point data is published for this venue yet; plan on ground-supported LED or ask the venue for its rigging plot. 4 of the 23 rooms sit under 3.5 m, which rules out flown LED there and limits ground-stacked walls to about 6 rows of 500 mm tile.
Data source
