Stairs: lay out risers and treads from your total rise. Rafter: get rise, rafter length, and angle from a roof pitch. Spacing: space pickets, balusters, or joists evenly across any run.

Stairs and Rafter now live under a single Framing tab, joined by two new tools — Rake for raking-wall stud layout, and Radius for curves between two walls.
