Spire Stairway Detail with Treads, Risers, Supports and Dimension View

This AutoCAD DWG file presents a detailed spire stairway drawing with precise tread widths, riser heights, support structures, handrail placements, and dimensional annotations ideal for architectural and structural planning. The drawing illustrates the geometry of spire stair treads, curved stringers, landing plates, central support columns, anchoring points, and railing assemblies with clear measurement tags that help architects, structural engineers, builders, interior designers, and CAD professionals coordinate stairs within complex vertical circulation schemes. Each element, including tread spacing, riser profile, handrail height, and section cut measurements, is accurately detailed to support seamless integration into AutoCAD, Revit, and other CAD platforms for execution planning.
