Award Winning Spiral and Helical Staircases.
Helical Stair Geometry
Choose a tool, then click snapped points on the A3 drawing.
Panel lift is the bottom offset from the stair baseline. Panel height is the visible height from bottom edge to top edge. Drag the panel view to pan and wheel to zoom. Panel DXF exports the outer face curve.
Native DWG is a proprietary binary format. The DXF exports open in AutoCAD, DraftSight, Fusion, Rhino, and similar tools, then can be saved as DWG there.
Treads are one less than risers. The tread tab mirrors the printable layout with the lower clipped plan under the top view, and the front view is projected from the live 3D geometry.
