Rotation and Shape Gradients

Rotation and Shape are separate Gradient dimensions. Rotation changes orientation across the pattern. Shape changes instances from the base Shape toward a target Shape.

Create a Rotation Gradient

  1. Start with a directional Shape such as an elongated Rectangle. A Circle will not show rotation clearly.
  2. Enable Gradient and select Angle.
  3. Choose Point for a local rotation field or Line for a directional transition.
  4. Add a control and keep Mapping Mode on Clamp.
  5. Adjust the center rotation, influence range, direction, and curve.
  6. Inspect the complete outline of rotated instances, not only their center positions.

The example uses a Line control with Center Rotation 70° and an Ease In-Out curve. Rectangles rotate progressively around the line influence field.

Create a Shape Gradient

  1. Confirm the base Shape in Shape Style.
  2. Enable Gradient and select Shape.
  3. Choose the target Shape and set its available parameters.
  4. Add a Point or Line control.
  5. Adjust Influence Radius, mapping, and curve until the transition region is clear.

The screenshot transitions Circle instances toward a five-point Star near the control point. Target Shape settings such as Points, Inner Ratio, Corner Radius, and Rotation affect the result.

Export Checks

  • Recheck Min Bridge around rotated corners and Star points.
  • Expect Shape transitions to create more varied geometry than a single base Shape.
  • Inspect inner contours when Ring is used as either base or target.
  • Verify closed contours and rotation in the target CAD/CAM software.

Troubleshooting

  • Rotation appears unchanged: Use a non-circular Shape and confirm Angle is active.
  • Every instance becomes the target Shape: Reduce the control strength or influence field and confirm the intended curve.
  • The transition looks abrupt: Increase the influence range or use a smoother curve.
  • Export becomes large: Reduce pattern count or simplify the target Shape.
