Array Polar

Repeats geometry rotationally around an axis. Produces count copies distributed over totalAngle degrees. When Closed is on (default), the copies wrap around evenly (360° / count); when off, the last copy lands exactly on totalAngle.

Sockets

geometry (in): Path / PointArray / Mesh / Toolpath. Required.
count (in): Int. Number of copies including the original.
axis (in): Vector3. Rotation axis direction (default [0, 0, 1]).
pivot (in): Vector3. A point on the axis (default [0, 0, 0]).
path, points, mesh, toolpath (out): The arrayed geometry on its matching output socket.

Parameters

Count: Number of copies. Default: 6.
Total Angle °: Sweep angle across all copies. Default: 360 — full ring.
Axis: Fallback axis direction. Default [0, 0, 1].
Pivot: Fallback pivot. Default [0, 0, 0].
Closed: When on, copies are spaced by totalAngle / count so the ring closes perfectly. When off, the last copy lands at totalAngle exactly.

How It Works

Copy k is placed at the input geometry rotated by angle_k around axis through pivot, where:

angle_k = k × totalAngle / count when Closed is on,
angle_k = k × totalAngle / (count - 1) when Closed is off.

Each copy reuses the same Rodrigues rotation formula as the plain Rotate node.
