The prompt
"Create a 3D structural model of a building's top floor with a symmetrical envelope-shaped (hip) roof. Base area: 15000x10450 mm with a 150x150 mm concrete perimeter beam. Divide the length with a 3100 mm high central wall. On each side, design a steel roof covering 4800 mm. Support it with four 100x100x4 mm columns connected by a 100x100x4 mm header beam. The roof rises 600 mm to a central ridge. From this ridge, place 100x50x3 mm steel rafters (on edge) spaced 1000 mm apart, sloping to the perimeter. Perpendicularly on top of these rafters, add 40x20x2 mm steel purlins spaced 400 mm apart for corrugated metal sheet installation. Include mirrored staircase shafts at 3100 mm height
