Free Stair DXF Generator for CNC Manufacturing

Our DXF generator creates precision cutting files for CNC manufacturing of staircase components. Each part is exported as a separate DXF file with exact dimensions, ready to load into your CNC machine or CAD software.

The generated DXF files include all staircase components: treads (step surfaces), stringers (side supports), risers (vertical backs), and custom winder shapes for turned staircases. Each file is properly scaled in millimeters.

DXF (Drawing Exchange Format) is the industry standard for CAD file exchange. Our files are compatible with AutoCAD, SolidWorks, Fusion 360, and any CNC control software that accepts DXF input.

To generate DXF files, simply configure your staircase using any of our calculators, then use the export function to download a ZIP archive containing all component drawings.
