# Fusion Stair Designer > Fusion Stair Designer is a CCSOFTCZ add-in for Autodesk Fusion on Windows and macOS that designs timber stairs parametrically and prepares their production documents, with optional Fusion CAM machining preparation including NC files. Canonical product page: https://www.ccsoftcz.com/fusion-stair-designer/ ## Product scope - Current version: 0.24.0. Runs inside Autodesk Fusion on Windows and macOS; it is not a standalone application. - Designs straight stairs and L-shaped stairs with a landing, including railings. - U-shaped stairs with winder treads are available as a geometric preview only. - Exports a production PDF report, a ZIP package of DXF drawings of the individual parts, and STEP. - The Design + CAM edition adds CNC machining preparation in Fusion CAM including NC files. - Built-in offline help; new versions are offered directly in the add-in. - The add-in does not assess structural design, compliance with building regulations or headroom. The user is responsible for the design. - The NC output is not approved for any specific machine. Before machining, it must be simulated and checked in Fusion. - Manual changes made to the model in Fusion are not carried over into the exports (PDF, DXF, CAM). ## Trial, editions and pricing - Trial: 3 days from the first start of the add-in, everything including CAM. Afterwards the commands require a licence key. - Design: EUR 590, one-time licence without a time limit. Everything except the CAM panel. - Design + CAM: EUR 1,290, one-time licence without a time limit. Everything including CAM. - Both editions include future updates. Autodesk Fusion is required and is not included. - The licence is tied to the e-mail of the Autodesk account signed in to Fusion and works on every computer where Fusion is signed in with that account. ## Primary resources - Product page: https://www.ccsoftcz.com/fusion-stair-designer/ - Language versions: Czech https://www.ccsoftcz.com/cs/fusion-stair-designer/, German https://www.ccsoftcz.com/de/fusion-stair-designer/, Spanish https://www.ccsoftcz.com/es/fusion-stair-designer/, French https://www.ccsoftcz.com/fr/fusion-stair-designer/ - Download for Windows (FusionStairDesigner-0.24.0-windows.exe, 316 kB): https://github.com/MarousSkotous/FusionStairDesigner-releases/releases/download/v0.24.0/FusionStairDesigner-0.24.0-windows.exe - Download for macOS (FusionStairDesigner-0.24.0-macos.pkg, 312 kB): https://github.com/MarousSkotous/FusionStairDesigner-releases/releases/download/v0.24.0/FusionStairDesigner-0.24.0-macos.pkg - All versions and checksums: https://github.com/MarousSkotous/FusionStairDesigner-releases/releases - Sample project report: https://www.ccsoftcz.com/fusion-stair-designer/assets/Stair_001_rev1_report.pdf - Order a licence: https://www.ccsoftcz.com/fusion-stair-designer/#order - CCSOFTCZ: https://www.ccsoftcz.com/ - Contact: info@ccsoftcz.com
