StairSmith - A parametric staircase design tool.

StairSmith is a free, browser-based parametric staircase design tool built for architects, architectural technologists, and building designers.

Choose from straight flight, single winder (L-shape), or double winder (U-shape) configurations and adjust every parameter — rise, going, width, tread thickness, nosing, balustrade details, and more — with a live 3D preview updating in real time.

Export your designs as IFC files for BIM workflows or DXF plans for CAD integration.

A built-in measure tool lets you verify dimensions directly in the 3D view.

No account, no login, no paywall.
