I already have a stair model drafted in FreeCAD, but the current dimensions no longer match the real-world space. I need the file updated strictly as a measurement adjustment—no design revamps or material swaps, just getting the numbers right. I’ll supply the existing .FCStd file plus photos and the latest site notes. Where exact figures are missing, you can help me confirm the right take-offs from my sketches or propose the most practical approach inside FreeCAD’s Sketcher/Part workflow. Deliverable • Revised FreeCAD model with all adjusted stair dimensions and saved constraints intact • A quick screen grab or PDF of the updated plan and section so I can cross-check before sign-off If this sounds straightforward for you in FreeCAD, let’s get it done.
