What I learned building Stair Flow Director

Start with the repeated job, not a feature list

The target users are Blender architectural visualizers, environment artists and interior blockout creators. The concrete problem was: Manual arrays and free single-shape generators leave floor-height fitting, flight division, landings and rails as separate reconstruction work

That framing kept the project focused on one observable result instead of a collection of controls.

Keep the workflow where the work already happens

The implementation uses Bilingual Blender 4.2–4.5 N-panel that generates standard editable mesh steps, landings and curve rails in a dedicated collection. The finished workflow lets a user Choose floor height and Straight/L/U flow, preview fitted risers, then generate the complete editable stair circulation.

The important design constraint was to make the result visible before the user commits to it. That is more useful than adding options that are difficult to verify.

Make the release testable

Before releasing it, I exercised the packaged build in the real target application through its main input, operation, and output states. Compatibility limits are documented alongside the workflow.
