Circle Array Modifier

Repeat an SDF shape in a circular pattern using domain folding. Circle Array is a mode of the Array modifier, accessed by setting Type to Circle.

Basic Usage

  1. Select a Chisel object
  2. Add an Array modifier via the Modifier panel or Pie Menu
  3. Set Type to Circle
  4. Set the Count for the number of copies around the circle
  5. Choose the rotation Axis and set the Radius

Parameters

Count

  • Description: Number of copies arranged around the circle (minimum 3)
  • Range: 3 to 50
  • Default: 2 (automatically raised to 3 when switching to Circle)

Axis

  • Description: The local axis around which copies are arranged
  • Options: X / Y / Z
  • Default: Z
  • Effect: Determines the rotation plane for the circular pattern

Radius

  • Description: Radius of the circular arrangement
  • Range: 0.001 to 100.0 (soft max 10.0)
  • Default: 1.0

Smooth

  • Description: Smooth blend radius between adjacent copies
  • Range: 0.0 to 2.0 (soft max 0.5)
  • Default: 0.0
  • Effect: 0 = hard union between copies, higher = smooth blending at seams

How It Works

Circle Array uses SDF domain folding, which rotates the evaluation point into a single sector and evaluates the SDF once. This makes the operation constant-cost regardless of the number of copies.
