| Settings | Tool Properties |
The Spiral Tower tool builds a whole climbable tower in one drag: a round wall (the shell), a spiral staircase whose treads sit flush against the inside of it, and solid floor slabs that are open only over the walkway. The underside of each slab steps with the stairs, so you clear it on the way up, and the stairwell is the way onto the platform at the top.
Drawing a tower

- Ctrl+Shift+Scroll wheel: the wall thickness.
Settings
| Setting | Type | Default | What it does |
|---|---|---|---|
| Sides | 3 to 64 | 16 | Shell. Wall facets per full turn. Treads and floor slabs are cut on the same divisions, so this is the one number the whole tower lines up with. |
| Wall Thickness | Meters | 0.5 | Shell. 0 builds the staircase and its floors with no wall. |
| Step Height | Meters | 0.4 | Stairs. Keep under the player's step height (0.457) or the stairs cannot be climbed. |
| Facets per Step | 1 to 16 | 1 | Stairs. How many wall facets each tread spans. Raise it for fewer, deeper steps per turn. Capped at a quarter of Sides. |
| Walkway Width | Meters | 1.5 | Stairs. How deep the treads are, measured inward from the shell. At or past the inner radius the treads reach the middle and the spiral becomes a solid ramp. |
| Center Post | Check box | Off | Stairs. Fill the shaft the walkway leaves with a solid column. |
| Direction | List | Counter-clockwise | Stairs. Counter-clockwise or Clockwise, seen from above. |
| Floor Thickness | Meters | 0.25 | Floors. How thick each slab is. |
| Top Platform | Check box | On | Floors. A slab at the top of the climb, flush with the last tread. |
| Landing Every N Revs | 0 to 16 | 0 | Floors. A landing every this many full turns. 0 builds none. |
| Head Clearance | Meters | 2.0 | Floors. The headroom a climber needs under a slab; this sizes the stairwell opening. A standing player is 1.829 m tall. |
| Door Width (facets) | 0 to 16 | 0 | Doorway. A doorway at the foot of the stairs, this many facets wide. 0 builds none. |
| Door Height | Meters | 2.5 | Doorway. How tall the doorway is. |
| Alignment | List | Align to surface | Brush. Align to surface, or always the XY, XZ or YZ plane. |
| Collision Type, Layers, Mask | STATIC, 1, 1 | Brush. See Box. |
