What fits in Center Hall (CH)
With a 7.9 m ceiling, a flown wall of Absen PL2.5 Plus V2 (2.5 mm) runs 99 tiles wide by 12 high (1188 tiles, 49.5 x 6 m, 19800 x 2400 px) once you keep 1.5 m of trim under the bottom edge. That wall weighs about 9,266 kg and draws up to 190.1 kW (914 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
Published dimensions. Dimensions from the venue's published meeting-space specifications (source). Rooms drawn as boxes use published length x width; shapes are as published. Venue managers: send a floor plan to upgrade your listing to production-ready.
