StairSmith
Design timber staircases in 3D and export IFC4 and DXF
StairSmith is a browser-based parametric staircase design tool for practitioners. It lets you model straight, single winder, and double winder timber stairs with a live 3D preview. You can set rise, going, width, and shape kite winders, then export IFC4 models for BIM coordination and dimensioned DXF plans, elevations, and sections. Aimed at architects, technologists, surveyors, and contractors, it speeds early-stage design while leaving compliance checks to the user.
