The prompt
Create a parametric 3D CAD model of a minimalist slim steel loft staircase for a modern duplex house. OVERALL DIMENSIONS: Total vertical height: 3000 mm Maximum horizontal footprint: 1400 mm Overall width: 600 mm GEOMETRY: Straight, steep staircase configuration Two parallel slim rectangular steel stringers Uniformly spaced individual steps Minimalist steel construction Integrated handrail system Clean and symmetrical geometry MATERIAL: Matte black steel Rectangular hollow steel sections Simple flat steel treads CAD REQUIREMENTS: Use precise dimensions in millimeters Create separate solid components for each step, stringer and handrail Keep the geometry editable and parametric Avoid decorative details Create a clean watertight solid model Exportable as STEP format IMPORTANT: This is a conceptual architectural model. Do not assume that the steep geometry is safe for residential use. Flag any dimensions requiring building-code and structural review.
