Section 1

Treat winder geometry as a stair system, not a side calculation

Winder stairs need connected control over turn geometry, treads, and overall stair behavior.

  • - Keep winder groups tied to the full stair layout and level transitions.
  • - Support L and U style winder workflows inside one stair workspace.
  • - Use plan-first editing so turn geometry stays understandable during iteration.

Section 2

Review geometry before it becomes documentation

Winders get risky when layout decisions are hard to inspect.

  • - Make tread distribution and walkline assumptions easier to inspect and revise.
  • - Pair winder geometry with stringer, railing, and clearance planning.
  • - Use revision-safe updates to compare alternate stair solutions cleanly.

Section 3

Generate outputs from the same winder model

Complex stairs still need practical outputs for field and review use.

  • - Generate stair blueprints, material schedules, and technical outputs from the same winder project.
  • - Track stale outputs whenever the turn geometry changes.
  • - Support publishable snapshots when a project needs outside review.
