Staircase Section Detail CAD Drawing 1:20 Scale with Dimensions

This staircase section detail AutoCAD drawing presents a clear and technical 2D sectional layout prepared at a 1:20 scale for architectural and construction use. The CAD file includes multiple sectional views illustrating stair tread and riser geometry, landing transitions, and edge detailing. Dimension annotations are clearly provided to define riser height, tread depth, nosing projection, and overall stair profile. Material layers and section hatching differentiate structural concrete, finishes, and support elements, allowing accurate interpretation during design coordination and site execution. Reference markers and section symbols are included to maintain drawing clarity and consistency.

The drawing also explains stair construction details such as step buildup, side support conditions, and junctions with adjacent structural elements. Vertical and horizontal measurements are drafted to scale for direct use in working drawings. This AutoCAD DWG file is useful for architects, civil engineers, interior designers, and builders involved in residential or commercial staircase design. The drawing supports detailed stair planning, construction documentation, and quality control. Accessing this file through a Cadbull subscription allows professionals to edit and reuse the drawing in AutoCAD, Revit, 3D Max, and Google SketchUp workflows.
