Art Gallery Designs AutoCAD DWG with Dome Hall 40x30m Layout

This art gallery design AutoCAD DWG file presents a detailed architectural drawing prepared for a building layout of approximately 40x30 meters with a central dome exhibition hall. The floor plan includes a main circular gallery space measuring nearly 18 meters in diameter, surrounded by peripheral display corridors of about 3.0 meters in width. The layout also shows entry lobbies, ticket counters, storage rooms, and service areas with clearly defined circulation paths. Wall thickness is maintained at approximately 250 mm for structural stability, while column spacing averages 5.0 meters to support the roof system. The drawing includes sectional hatching, standardized symbols, and precise dimensioning for professional documentation and construction reference. The file also contains front elevation and sectional views illustrating a dome height of nearly 14 meters, façade arches, and window placements for natural lighting. Floor-to-floor height is maintained at about 4.0 meters for exhibition comfort and visual clarity. This AutoCAD DWG format allows easy editing, scaling, and coordination with AutoCAD, Revit, SketchUp, and 3ds Max platforms.
